MSN Key port 80048820 error

A friend had the following problem on his machine and of course, I was called to the rescue. I had tried all the normal things, reinstalling MSN, turning off firewalls and anti-virus software but still no go. The machine could browse the net fine, except and MSN messenger would not work.

This was the error. (With error code 80048820)

"Sorry, we were unable to sign you in to the MSN Messenger at this time. Please try again later.
To let us try and troubleshoot the problem, click the Troubleshoot button."

Next step was the googlemobile. Google informed me that quite a few people have had this error/problem. Most suggested it was the firewall settings, which I found to be wrong.

Solution 1
In my case I reinstalled the network card and strangely that seemed to do the trick! If it doesn’t work for you, give the below solutions a try.

Solution 2
Try removing any proxy settings, you can do this by following these steps.
1) Open up Internet explorer
2) Click the tools menu, then Internet options
3) Select the connections tab
4) Click the “LAN Settings” button
5) Ensure “Automatically Detect Settings” checkbox is ticked
6) Untick “Use a proxy server for your LAN …” if checked
7) Click ok, then ok
8) Start up MSN and give it a whirl!

Solution 3
Check your windows System clock and ensure it’s set to the correct time and date.

Solution 4
Has your Norton subscription run out? Some people have reported this will stop MSN from working. (Not sure why … so don’t ask)

Solution 5
You can try resetting your Internet Security properties to defaults.
1) Open up Internet explorer
2) Click the tools menu, then Internet options
3) Select the security tab
4) Click the Restricted sites icon
5) Ensure or isn’t on that list. If so, remove it. Click ok.
6) Select the Internet Icon and click the “Default Level” button. This will return your Security settings to the default level.
7) Click ok, close down IE and MSN and then try launching MSN.

Solution 6
Try and isolate the problem, find out whats causing the the error. If you have norton, turn it off. Does the problem still appear? If not, it looks like Norton is blocking it. Read the Norton manual and find out how to allow programs to access the Internet. This applies to Zonealarm, and other firewall programs.

Solution 7
Try to register softpub.dll using regsvr32.exe.

1. Press the Start menu then select Run
2. Type: regsvr32 softpub.dll
3. Press Enter & Restart Messenger.

Solution 8
1. If you have Norton installed, run LiveUpdate, make sure you have most current version.
2. Delete your Quaruntine and Backup files in Norton.
3. Reboot computer

  1. Chris says:

    I got the same problem today and I tried everything as you had done. Finally I found that the problem was caused by the IE-Tab extension for Firefox. It checked the checkbox for proxy sever in IE internet option->Local area network setting. Unchecked the checkbox,thing is ok!

  2. Jamsi says:

    Ah I see. Yes that could cause it as well. Thanks for the info Chris!

  3. Rachael says:

    iv got exactly the same problem except with mine iv tried EVERYTHING and NOTHING seems to be working.
    Even when i go on to i sign in on there and it says the page cannot be displayed.
    Any suggestions ?

  4. Jamsi says:

    Have you tried uninstalling your network card, rebooting and letting it reinstall?

    It could also be spyware messing with your settings, run a full scan using Spybot. You can download spybot from here –

  5. mort says:

    The reason it was happening for me was incorrect proxy details in IE. Make sure it is set to automaticly detect, or direct connection to the net.

  6. dan says:

    ive tried everythikng u guys have said and even more any more suggestions people? many thanks

  7. Dom says:

    I had this problem too. I did all the stuff people have said, but to no avail. I tried a system restore. Nothing. My problem was Norton. Once I uninstalled, everything worked. I don’t know what it was. Even when I disable Norton it didn’t work, just after I uninstalled.

  8. Louise says:

  14. Adrian says:

    i had another think about when this situation last happend to me, i think it was when i was messing arround with Hijack this, and other anti spyware tools, i was just wondering if any of you would have been using a tool similar to this, and maybe you disabled a service needed by the computer that was labled spyware.

  33. Michelle says:

    My msn randomly decided to stop working, I did everything that was suggested, even removed my Norton (which had expired) but no luck. So, I looked through my files and found MSN 7.0 vesion. Uninstalled 7.5 and went back to 7.0. Now, its working fine. :)

  34. Jamsi says:

    Glad to see it worked!

    Glad to see it worked also!

    Uninstall Norton .. right now and buy a better AntiVirus product. Have a look at a AntiVirus product called “Kaspersky”. Top notch software.

    I did the exact same thing at one point :)

  35. pat says:

    how do you reset the card thing? please help

  36. Jamsi says:


    Under the windows control panel, open up “system” then select the Hardware tab then select Device manager and you’ll be able to uninstall the network device under that.

  37. Nauman says:

    Great. Thanks it worked. I had date time problem.

  38. Lizzy says:

    Have exactly the same problem, its driving me mad. Had tried everything and because people had mentioned norton i figured it might be McAfee as my subscription had jsut run out so tried to unistall it but it says there was an error while trying to unistall. Can’t get rid of it now! What can i do?

  39. Admin says:

    We are really sorry for the current errors.The MSN messenger is undergoing some critical updates and will be full functional within a few days.It seems to clash with IE and Norton Antivirus Software.
    Sorry for the Inconvenience.

  41. J.A. says:

    Recently, I installed the Kaspersky Anti-Virus and scanned my PC. After it had deleted many corrupted files, my MSN does not want to connect anymore. When I press “Sign In”, nothing happens. In the “Connection troubleshooter”, everything looks fine except the key ports, which it displays a yellow triangle with the ! sign.

    Can anybody help, please? I tried everything, even uninstalling Kaspersky.

  42. charles says:

  46. Dixon says:

    Waynem’s way on Mar 22, 2006 did work….update the MTU setting on Router made my MSN up and rumming again. Thanks you all…^_^

  47. Justme says:

    i tried all of the solutions above and many more from other pages and i searched for the problem myself but nothing happened still this error. I changed the mtu size because i think the linksys router causes the problem due to some unconventionnel settings or whatever.
    The problem happened first time when i connected the PC to a new router(linksys wifi router)and i checked all settings but didnt find any solution. on other pages i read that linksys routers can cause problems with msn and that they can be solved, but i cant find one.
    Some pages(all micorsoft pages like or or or)aren’t working either.
    Please help
    i cannot buy a new router just because of msn but i need msn and not trillian or whatever
    Thx guys

  48. John says:

    I’ve had the same sign in problem. Until now I had a Messenger file on my desk-top & would just reinstall when ever I had problems. Now this won’t work anymore. Also a friend who has MSN email, when ever she mails me, the email comes through with no sender, no subject & a whole page full of numbers & letters, there’s some connection to this messenger problem here also.
    My solution was to uninstall MSN messenger & install windows messenger instead.
    I’ll what for a newer version of MSN to come out.

  49. pascal says:

    i did everything above but nothin
    at my job no msn today and now that i come home no msn at home this is f***** up

  50. Insignia says:

    what it is me and a m8 of mine have come down with the same problem on the same day and the only thing our pcs have in common is we both use ntl broadband

  52. MackDaddyP says:

    I’m a military man that does this stuff for a living… it’s most likely a Norton issue.

    1. Run LiveUpdate, make sure you have most current…

    2. Delete your Quaruntine and Backup files in Norton.

    Close and restart MSN Msgr…. worked right away for me.


  53. andy says:

  54. Louise says:

    Help me please! I followed the instructions & it didn’t work!I don’t know what NORTON is so I can’t check it and when I try to sign in TROUBLESHOOT comes up and says there is something wrong with my KEY PORTS which I dont have a clue what is it.

  55. jonny says:

    I don’t know if any of the above things will fix the problem – I haven’t tried them. I use a Netcomm NB1, and managed to solve the problem by changing MTU size.

    I logged into the modem, changed and enforced the MTU size at 1500, and then applied setting. Works a treat.

    Hope this helps,

    all this stuff about wrong clock settings norton dll files etc… i think is rubbish.i have a router and my msn won’t work.connecting modem directly to pc and hey presto! msn works great.the problem seems to be this new version of msn messenger and windows messenger live is conflicting with settings that most routers use.older versions of msn work ok so if some techy at msn could look into it then all of our problems might be solved.

  83. Kayleigh says:

    Hello I Have a problem. Either Spyware or Key ports. My computer when i attempt to sign in msn messenger says TROUBLE SHOOTER and when i go to trouble shoot it says key ports with a hazard sign next to it.. and does not let me into the internet i don’t know what to do. Should I go and get it fixed or reboot my computer because i have heard that spyware ruins your computer.

  84. Toni says:

    I have the same problem as most of you guys do.
    I run MSN Messenger 7.5 on my computer and just until recently it has stopped working. Error 80048883. The window pops up. Everyone has seen it. Then I click Troubleshoot. The keyports!! How do I fix this. I’ve tried absolutely everything.

  85. fenrhir says:


    MSN Messenger was refusing me to connect since i’ve connected my laptop to a wireless router.
    Problem was not the router configuration (MSN MEssenger working on other pc), neither laptop configuration (MSN Messenger working with other Internet connections).
    According to MSN Messenger Problem Resolution Tool, no problem : all tests ok.

    So ???

    So, it’s strangely the use of that specific router – Alicebox Hitachi, provided by my ISP “Alice ADSL” in France – WITH my software firewall (Sygate Personal) that was preventing MSN to connect.

    Why? Don’t know… With other firewalled wireless routers it’s work fine.

    So : if you have a strange problem but u think your firewall/virus protection is ok, still try to unactivate them…

  86. Emily says:

    Hia, my msn normally works fine, until the last couple of days it has randomly just been singning me out. i sign back in again and it does it again within the matter of 5 minutes. I went on it today and it signed me out after about 30 mins and now i cant get back onto it because when i click sign in it comes up with TROUBLESHOOT and then i click repair but comes up with a yellow triangle with a ‘!’ init! ive tried everything u guys have said except from uninstalling Nortan because i dont have that. What should i do??? help please xxxx

  87. Shane says:

    Problem uninstalling Norton: My Norton Antivirus 2004 and Norton Internet Security 2004 are expired and have ben for ages. My MSN has worked fine right up til last week, randomly stopped. I know I need to uninstall Norton), but the only Norton-type thing in Add or Remove Programs is ” LiveReg (Symantec Corporation) ” with “Remove” option. When I click this, it tells me I cant uninstall cause Norton Antivirus and Internet Security are using this product… ! Theres no option to uninstall Norton on the shortcuts or icons. So I logged onto Symantec website and it very helpfully directed me to go to…. Add or Remove Programs! Im ready to cry at this stage!
    It seems nasty Symantec wont let you have the option to uninstall until AFTER you update and pay them!!!! Which I refuse to do cause their product is RUBBISH!
    Anyone who knows how I can get rid of Norton please tell me asap.

    Shane, Dublin

  88. alex says:

  90. Georgie-anne says:

    Recently my msn has not been working. I have tried troubleshooting and a message appears saying there is a problem with my key ports. I have checked my Windows firewall which is allowing access and I do not run Norton. I have emailed Messenger Support but NOTHING they have said has helped me. This has happened before, but fixed itself…It’s now been a week and I STILL can’t sign into msn.

    Please help me!

  95. Kehoe says:

    I have recently got a belkin router, now i have some odd problems, there are several machines on the network using MSN, and only mine can not access MSN messenger i get the error code 80048820 80048439, now my machine is the only None wireless one my connects directly to the router, but if i unplug the router and connect my pc to the modem it works fine so i no that its the Router causing the problems, The routers firewall is off i tried adding the Ports,

    any one out there now how to get MSN working again ?

    Thanks Kehoe

  96. Jim says:

    The symptoms you have been experiencing may be the result of either malicious software, or a bug in the software.

    I’ve been through all the steps suggested above. MSN still thinks the Key Ports are blocked, even with the MS firewall turned off. The funny thing is that the laptop I was working on had messages popping up about revoked certificates at the same time MSN stopped working. Even tried installing the Messenger Live Beta. No dice.

    And of course and still work, and the available AV and spyware cleaners do not find anything wrong with this laptop.

    Only option left is to format and reinstall from scratch. That and chuckle at the joke “If Microsoft made cars the way they make software, we’d still be riding horses…”

  97. Jo says:

    I have to tell you folks, my computer’s been doing this for months, and I learned to live without it…heh.

    So i decided to figure out what was wrong with it, and stumbled across this nifty little page. Tried all the solutions posted, nothing worked.

    My solution? something that’s been mentioned at least once. MSN Messenger V. 7.0. uninstall 7.5, install 7.0. I now have MSN Messenger and don’t know what to do with myself!

    If you are looking for a good antivirus and firewall program, i highly suggest Symantec Security Client. Heaps better and that antivirus picks up bloody everything, from trojans to viruses. Cause it is a enterprise product, meaning use for buiseness purposs u cant really buy it for your ‘single’ pc. But u can pick it up a some torrent site. Try and type in Symantec Client, do a search on that and hey presto. U need a BTclient to download anything off thsoe sites. I suggest using Bitcomet do download the links given to you by the website.

  99. PEOPLE says:

    I found this KEY PORT problem to be caused by spyware. Do a sweep of your system with Weebroot
    “”Spy sweeper”", should pick up alot. Webroot spy sweeper is rated top antispyware product of 2006.
    yOu can aslso pick up this program from any torrent site for free. But if you like it BUY IT.

  100. Magic man says:

    i went on norton and it said it was blocking over connetions so i disabled norton and now msn works :D

  101. Bashar says:

    For some of you this should definitely work
    Put your windows xp cd in the cdrom and Click on start then run. copy and past this command with (NO Quotes) “rundll32.exesetupapi,InstallHinfSectionDefaultInstall 132 %windir%\inf\ie.inf” and press ok. This will reinstall Internet Explorer,now try to sign in.
    Good Luck…

  102. Bashar says:

    i tryed everything u suggested, still can’t get into MSN.

    this is what i get every time:
    MSN Messenger has made several attempts to sign you in. Your firewall may be blocking Messenger from connecting to the server. Please review your firewall settings. See the retailer’s instructions for more information.

    my norton has run out to, so could it be that then? but it ended awhile ago tho. and msn was okay until now.

  129. dric says:

    hi.. I did solutions 2-7 and did from any other sites. I don’t have an AV atm. I was using AVG before then I unistalled it but it didn’t work. I would like to know when you mean reinstalling the network card, does that applies to a wireless network card?

  130. dric says:

    Ok.. Well.. basically my problem was something about wininet.dll My AV thought it was a virus or something “trojan” so I accidentally put it into the “vault” then my IE and etc went crashing down. So what I did is uninstall the AVG, download a wininet.dll file then put it into “system32″ directory in your windows folder. THen now it’s working -_-’

    error code: 80048820
    extended error code: 80049439

    When i enter my passowrd – it shortens it down to 8 digits even though its much longer.

    I have the same problem with MSNL and MSN 7 – when it does a system check – it seems to stall on Key Ports for a while, I can not work out this why it would alter my passord and not connect to MSN.

    If anyone can offer some pointers, i have tryed everything on the above list also :(

    Thanks – Great site btw

  146. moony says:

    mine is still not workin i tryed this all:(:(:(:(:( i swear i am getting craza!

  147. Rabbit says:

    I could not log on MSN messenger anymore as wel as log in to my email account. I tried everything mentioned here and all have failed.

    Nothing worked until I found some forum, I don’t remember wich one but I do know I just had to replace “wininet.dll” found in “windows\system32″

    What happened was a trojan horse wich had corrupted this .dll and made me unable to connect to secured sites/msn-messenger.

    For those who have this problem and all solutions seem not to work, you can try “spysweeper” wich has a 2week free trial and sweep your system, recommended in “safe mode” by pressing F8 when your computer boots. Run full system scan (can take a while), and let spysweeper take care of your problems. Next step is to replace the corrupted .dll file wich can be downloaded for free here:

    It might be a problem to erase the corrupted file as windows uses this dll and u cannot delete it easely. I had to rename it and place the new .dll in place.

    Now I can connect my msn again. I hope this helps for other people too.

    This solved the 80048820 and 80048839 error.

    Good luck

  148. Kevin says:

  155. Paula says:

    I did solution 1 (correcting LANS settings and it worked…however, the next day it was back to the key port problem. I’m not a computer wizard by any means so although i have mcafee firewall and I have checked it I have no idea if there is something blocking & I do not know how to uninstall. Wouldn’t this be dangerous? Neither do I know how to uninstall the network card and reinstalling. Is that something to do with the .NET Password? Can anyone do a step by step for simpletons so that I can sort out this problem?

  156. Jess says:

    I am going insane!My other computer lost not only my msn connection but my A.I.M. and all my other internet connection. I can not access any sites on firefox or Internet Explorer. How can I restore my internet connection? I tried repairing the connection with the Local Area Connection but it did nothing. I also tried all of the steps here because my MSN troubleshooter is telling me that the problem exists in the key ports.I don’t even know what a key port is! Please help!

  160. Steve says:

    I had the same problem. Read through all the fixes on this page but they didn’t work. I new there were still remanants of Norton on the PC becasue CCleaner ( showed it in the program removal section.

    So I tried this free Norton removal tool:

    And guess what. It completely removed eveything to do with Norton and MSN started working again :)

    Hope this works for you too. Good luck.

  161. Steve says:

    I also found a similar problem on another machine where there was one login that wouldn’t work and gave the same error. Other logins on same PC worked. No Norton on the PC this time.

    To resolve this one I upgraded the browser to Internet Explorere 7 and the problem went away.

    Another strange one, but true.

  162. Ffriday says:

    I dont actually think this is a problem with MSN itsself, but my computer, but i am posting in this messanger forum as MSN has given me the best feed back as to what the problem is, i have contacted my ISP, but they were little to no help, as they said it was most likey a problem with my PC, and didnt offer any solutions.
    I use a Satellite connection, and every so often my connection doesnt exactly fail, i am just unable to use it; it still claims to be connected, but pages dont load and MSN messages are not delivered, MSN frequently diagnoses this as a ‘KeyPorts’ issue, but occasionally a DNS problem, error messages vary, but here are a few commom ones i have recorded:
    I have tried running “regsvr32 softpub.dll”, i have scanned for viruses, i have disabled my fire wall and other protections, i have played with my proxy settings, i have done a system restore (restoring to an earlier time), and reconnected over and over again.
    Please Help!!!

  163. Gaurav says:

    my problem was that the same machine would connect to windows live messenger when connected directly to the modem, but when i connected through the wireless router, it would give error 80048820 extended error code 80048439. Solution is simple, change the MTU (Maximum Transmission Unit) from 1500 to 1400.

  164. Gaurav says:

    nooo it didnt :( same error

  183. TheBoyMid says:

    I’ve just got this problem fixed. I tried all the above and was getting nowhere. Messenger worked without my router, but not with. I thought I’d tried everything. In the end it turned out that although the PC’s time and date were correct, the router’s weren’t. MSN checks checks the device that is connecting to the Internet… i.e. the router and not the PC. If you have a router, open it’s admin page and check the date and time!

  184. Rainmakerart says:

    hi, guys, i’ve been getting the same error codes (80048820 and extended 80048439) past two days but mine is a strange case. There are two laptops in the house. 5 days ago, Messenger Live was working on both. 2 days ago my laptop showed the MSN Messenger errors but the 2nd laptop was not home. Anyway, I thought the problem is on mine only.

    I found this page and several others and I tried every solution listed here and other pages. When the errors started, I was using Messenger 7.5. I went back to MSN 7 but it gave me another set of error codes so I decided to move even further forward and I am now on Windows Live Messenger 8.1. I still have the same errors. I tried the clock change, I am certain of my proxy settings, and I always test with Norton Security disabled. I have registered the DLLs. I also checked my host file, tried using the wired connection to my D-Link instead of wireless, etc. and a number of other things.

    Here is the first strange thing: the 2nd laptop became available last night. I ran MSN Messenger and it ALSO showed the same errors! Yesterday afternoon, that 2nd laptop had been running messenger without a problem while it was connected at an office network.

    I ignored that for the moment and tried a few more things, including uninstalling my wireless card driver and reinstalling. Well, to my surprise, MSN messenger suddenly worked!

    Now here’s the next strange thing: the 2nd laptop ALSO worked! So I think the uninstall/install of the driver was just a coincidence.

    I just left the situation as is and I did not care since everything was working again. That was last night. Well, this morning … both laptops were back with the same errors. I tried the uninstall/reinstall ‘trick’ just to be sure but it did not work this time, as I expected.

    So I figured it must be the D-Link wireless router, which – other than our ISP’s own network – is the only thing common to the two laptops. I decided to change the MTU to 1400. I also adjusted the clock on the router, just to be sure. It did not work.

    By the way, I went to and I could not get MSN Web Messenger to work either. IE 7 gives me a “cannot display the webpage” screen and offers a link to “Diagnose Connection Problems”. I clicked this link and it did not find any problem with my connection (which is what I expected, since I can access the HTTP, FTP, and POP sites normally.)

    And so, both laptops at home are still stuck with the error and cannot sign in to Messenger.

    Anymore ideas, guys?

  207. Andrew says:

    I figured out what it was on mine. First I did Solution 2 and then I checked up on the norton thing. There is a little icon on the bottom thats greenish on the top and bluish in the bottom almost in the shape of a ball. Right click it and disable and I was all good.

  208. Kokulan says:

    That was very useful and it worked as u explained.
    Thanks again. I really appreciate it.

  209. g_ o cara says:

  211. Very Grateful says:

    THis happened on a friends computer. Sure enough, it was Norton’s fault. On the 31st day of the 30 day trial, norton not only blocked MSN messenger, it ALSO blocked the ports used by COMPETING anti-virus software programs! In the end I had to boot into safe mode, and do a controlled lobotomy of anything norton. THen it worked fine.

  212. Maxie says:

    i have tried all and stil not working HELP!

  216. Pedro says:

    I had the exact same problem (key ports test didn’t succeed) and the wierd thing was at my home desktop msn connected fine, but with my laptop it gave me the 80048820 error. At work I could connect (with the laptop) fine without any problems whatsoever…
    Anyway what did it for me was UNcheking the “server site revocation” in IE7 avanced settings.
    Thanks a bunch and good luck to everyone else who is still strugling.

  224. Selena says:

    If you are having troubles signing in…before you start messing around with your settings….check the status of MSN first….it MAY be their fault!
    Good Luck

    Service Status
    This page will be updated when information becomes available.

    The .NET Messenger Service is temporarily experiencing difficulty. You may be unable to sign in. Please try again later.
    Last Update: 4/12/2007 11:00:00 AM Pacific Time (GMT -8:00)

    Got that from checking messenger live key ports error 80048820 extended error 80048439, I desided to check their server status…

    This error also means the key ports of their server are down heh.

  226. Coolio Wolfus says:

    And yes and live help both have busy server warnings, sounds like M$ is trying to upgrade their servers to vista/longhorn server heh and having the usual issues.

  227. Selena says:

    lol, they’ll be doing that all through the summer just like road works. They upgrade them to work then all of a sudden, Vista has another bug to correct then all the servers will have to be serviced again lol.

  228. ms. angry says:

    i am just gonna go crazy if i dont know what to do about this !!!

  229. RealDreaM says:

    I changed the MTU but it doesnT work and the other strange thing is that I was having another message instead of troubleshooting.. it’s like;81000314

    But the troubleshooting message appears too, and it is like; 80048820…

    oh no what da f**k. I just right now got into the MSN while I’m trying..i think the problem has been solved by itself…

    Yes it works…I restarted the router and changed the MTU to what it used to be [1492]…SO I’M RECOMENDING THIS:
    -I disabled the windows security wall
    -Then while I’M writing my problem here, on the other hand, I tried to get in the MSN..But suddenly it worked..

  230. omfg! says:

    omfg ive tried evryfin 2 get on it :@:@ ive took ma battry out n evryfink u lot got nemore suggestios ??

  231. RealDreaM says:

  234. Dan says:

    please someone help me why cant i sign into msn messenger or the my ebay section of the ebay website PLEASE SOMEONE ANYONE HELP ME has been like it for 3 days

  235. KANNA says:


    tyr uninstalling your messenger, and downloading it again from the MSN website.

  236. jwstoop says:


    I had this same problem and finally i figured out what it was. I took away the router and connected the pc directly onto the incoming UTP cable. That did it, so the problem wasn’t caused by my pc, but by the router, a Linksys WRT54GL in my case (Linksys seems to have this problem with a couple of routers)!

    So the people who have this problem and are using a router should try taking the router out of the network and connecting the pc directly to your modem. If this solves the MSN error, then you can do the following:

    1. upgrade the firmware of your router.

    2. If that doesnt work or there is no new firmware, set your ‘MTU’ value in your router to 1400 or 1450. That did the trick for me!

    Good luck from a sunny and hot Amsterdam!

  237. jwstoop says:

    Hmm next time I’ll read the other replies first ;-)

  238. MrHuyneeh says:

    i cant really get this thing working, norton has stopped and expired, the net is workin fine, online games workin fine, any else i missed? i tried the “solutions” and they didnt help much… wanna un-install norton unless i have to…any help y’all?

  239. MrHuyneeh says:

    i read through the comments,[ima fast reader], and now nothing helps, im as angry as a person talking to an indian man trying to offer u a Telstra membership from FREAKEN MUMBAI! GARGH! HELP!

  240. Dan says:

    its norton doing it all u have to do is get the new norton 2007 and renew it then everything will work fine again

  241. Raphael says:

    Thanks alot! solution 2 solved my key port problem.

  242. Spencer_boffin says:

    ok folks dont want to be a party pooper but ive been hugging this problem to myself and not letting on. Reason ITS COMMON and i get paid to cure it. Ok It should work but each PC is individual with individual problems. this is the most common. Open Internet explorer (Example here is for IE7) goto tools, then internet options then advanced. Then scroll down and uncheck (if checked) check for server certificate revocation. Then scroll a bit more to see if SSL 2.0 and SSL 3.0 are Checked (important) if use SSL 2.0 isn’t checked then check it!!!! theres 9/10 is your problem. Also use SSL 3.0 and use TSL 1.0. Check date and time now. IF this dosen’t cure it then theres deeply laying problems. Good Luck and happy browsing -Spencer_boffin

  243. Dan says:

    just get the new Norton Anti Virus if u already have norton installed and it has run out then u all have to do is renew it overwise re-boot in safe mode and take everything out with norton on as it is norton who are causing the problem as u may have noticed the reminder thing hasnt come up lately thats because they have given up trying to get u to renew and have decided to cause this problem

  244. Ali says:

    Hi I had the same trouble but not just with msn , also yahoo and AIM , im desperate i uninstalled norton, and installed kaspersky, i checked for all kind of malware and nothing, I think my trouble is a virus , cause when I use Firefox everything is ok and when i start the machine on the Admin session only on safe mode, i dont have the trouble, but when i go to my session even on safe mode, i have this problem and my home page on internet explorer is redirected to a crazy chinese site, please if anyone can avoid me to format and reintall windows please tell me Im getting crazy .

  245. Meridiana Nolan says:

    Hey. i have this problem and i have tried everything. I have Nortons and it expired a couple of months ago. I realise that it is probably Nortons that is causing the problem, however, i cannot uninstall it because i do not know my password, the program came previously installed with my computer. Also my computer will not let me access any of the symantec websites. it comes up with “this page cannot be displayed”. I am very stuck and don’t know what to do. Is there any other possible way i can uninstall Nortons or fix my msn. Or will i have to renew my subscription to Nortons? If i do so will it definaltely eliminate the key ports problem?
    Please get back to me soon
    thank you, Meridiana xx

  246. Barry says:

    I just recently upgraded to windows vista however, this problem precedes the recent upgrade. I do not run Norton or McCafee. When I try to log into MSN, I get an error with the default gateway. Then when I do get passed that (don’t ask me how), I get an error on the Key Ports. For some odd reason, I think that my modem has something to do with it. But I’m not sure. Does anyone have this problem? If a solution requires going to ‘Run’ on the start menu, I don’t have it. I also run Firefox (latest version and have everything updated.

  247. BIOHAZZARD says:

    I FINALLY figured it out.

    I tried every single thing mentioned on the MSN help section regarding this problem, but nothing seemed to work. I was curious about the Norton thing, and that’s the problem!!! Even if your Norton subscription has run out, try just running Norton Internet Security and then try MSN. =) It’s working now for me.

    Maybe someone with more of a technical background can figure out why it works that way. Something to do with the registry maybe?

  248. amit says:

    i got the same problem, actually my problem was worst , i was not able to open, hotmail,microsoft n mcafee websites as well the msn or live msngr even after doing the full format of computer n
    spending hours with tech guys, but when i checked my modem under my device manager it shows me someone elses name in my computer as the name was like this ” ctx modem for ali” n i dnt khow who this fucker i disabled it as it was not uninstalling and tried again , it solved my problem , everything started worked right at the moment , now 1 this is left i get to know who this fucking ali is as i will call my tech support again , try disabling ur modem , it worked for me, may b for u….2

  249. Brittany says:

    I have exhausted everything except the network card thing.

    but dont really know wat the problem is with the key ports..
    would b nice to finally know wats happening cause the troubleshooter even dont know wat the problem could b..!!! so its probably wiz the ISP or hotmail itself..

    neways if someone gets to understand all this let me know..

  256. Vicki says:

    “I had tried all the normal things, reinstalling MSN, turning off firewalls and anti-virus software but still no go. The machine could browse the net fine except msn messenger would not work”

    Those are my only problems, none of your solutions have worked. The only one I haven’t tryed is your first because I have no idea how to reinstall my network card lol

  278. Ryan13yr says: works fine

    Uninstalling then reinstalling did the job for me

    Thank You

  287. Kenneth says:

    I got the same problem yesterday. I try all the solutions being offered above and it still didn’t work. Finally I found why the problem is:

    Start -> Control Panel -> Windows Firewall

    Because I installed Norton 360, I turned off the windows firewall. However, when I look into the Exception tab, I found the ‘Windows Live Messenger 8.1′ and ‘Windows Live Messenger 8.1 (phone)’ were checked.

    What I do was uncheck both of them and run MSN again, everything back to normal. It seems that this is the problem in my case.

  288. kaitlin says:

    Hi i’m having the Key port problem, and i can’t get into any secure sites like hotmail, facebook, or my university online system(which is really bad) and msn keeps coming up with the key ports error, but now it also says i am having dns errors. Any suggestions?
    thanks so much!

  300. Wye734 says:

    Thank you so much, solution number two fixed it my provider had some auto proxy going and it fucked up everything that was MSN. I just wanting to say thank you because the Microsoft site didn’t help at all.

  301. Alice says:

    Hi I had this problem after I uninstalled norton 2006and I contacted help desk staff. Apparently it is an issue with norton 360. What I did was IE settings advanced options and then first. Uncheck the options “Check for Server certificate revocation (requires restart)”Also “Check for Publishers certificate revocation”. I unchecked the second one and then msn worked bingo!

  302. Alice says:

    Not sure why it works, u can recheck the boxes after apparently as well. Just some weird quirk I suppose

  303. Diva Disaster says:

    I unchecked all my previously checked boxes and it connected right away.

  304. Aftab ulhaq says:

    I have tried to reset internet setting but it could not work for me.Actually my anti Virus whish is Kaspersky was blocking MSN messanger i just disabled it for a moment and messenger got loged-in.thanks for you guidlines..

  305. Alex Seif says:

    Hey everybody,
    I think I know the problem to this, I have tried more than what was posted in this article, and then came to find that when Microsoft decided to go live it changed the directory of the messenger from to %program files%/live/messenger and hence your previous firewall and anti virus settings do not comply.
    All you have to do is edit you’re anti virus and firewall to the new directory..
    I use kaspersky and windows firewall, all I did was delete the old entries and had them re initiate notifications to allow the messenger.

    Jamis I’m sorry to tell you have just rewrote the solutions out of Microsoft’s own troubleshoot, you have added nothing but you’re own words..

  306. hanna says:

    I’ve tried all of the solutions, but none are working. For some strange reason my starter page works when I open Mozilla Firefox and also I can search things on Google at a fast speed. But when I try to go to links or type in addresses everything goes incredibly slow! I have a wireless internet (if that helps)

  307. hanna says:

    Sorry! I’ve just realized that my error code is: 81000306 (i have no clue what that is)

  308. XLR8 says:

    To remove the proxy settings, click the “Tools” menu and then “Options…” at your Messenger main window. Then in the options screen click “Connection” in the list to the left. Next, click the “Advanced Settings…” button. You can try and uncheck all checkboxes in this screen except the one labeled “TCP” to let Messenger connect through a direct connection.

    ….Why do some write this as help when i cant even log in.. in order to actually change the options in my messenger I HAVE TO BE LOGGED IN but since this whole topic is about how people cant because of the error how does this help?

  309. annoymous says:

  315. CJ says:

    Has ANYONE come up with a solution yet? Tried all the fixes listed, and then some, but I still can’t access Yahoo, MSN Messenger, or my email on this computer. Been like this for about a month now…getting old.

  316. CJ says:

    Alright peeps…it’s 4:15 in the damn morning, but after putting in 20+ hours of trying in vain to fix this problem, I stumbled on the solution.


    Uninstall MSN Messenger, and run this:

    Then let it restart your PC and download MSN Messenger. Try testing your email first; my email was fine right off the bat, but Messenger took a few minutes to come around.

    If this works for you…then do your fellow sufferers a favor and post the fix in a thread where you’ve seen this problem.

  317. galz says:

    Im getting hopeless

  320. Tao says:

    Solution 5 worked great for me. Thanks for putting this up here!

  321. Mike says:


    I tried everything…..BUT I found another solution.

    In Windows Task Manager (Alt/Ctrl/Del) there for some reason another msnmsgr.exe running in the background. When there shouldn’t be – close them all . Restart Messenger – and that worked for me.


  322. Bhattacharyya says:

    Hey Guys,
    Im having the same problem , to make the matter worse my boyfriend has recently moved away to america , the only way for us to keep contact is through msn , and just my luck..It started playing up , I tried EVERYTHING your website says , apart from uninstalling that card thingy , i didnt understand that , i am currently uninstalling windows live messenger for an older version (7.5) to see if that works , fingers crossed.
    I miss my boyfriend :(

    1. Uninstalled all the MSN related program.

    2. download ‘MSN Messenger 7.5.0324′ and installed into your PC. pls goto the following link.

    3. after successfully installed, exit the old MSN program.

    4. download the latest MSN version and installed without uninstalled the previous version.

    Hi Sophie,

    Did you go through the solution list? Have you tried checking your system clock? What about Norton, do you have it installed?

    Most people find the answer after going through each solution listed one by one.

    Thanks, Now my msn is back up. :D

    Hey, I can log on to MSN Web Messenger but not onto Live. I run the trouble shooter and it comes up with hosts file error – your hosts file contains windows live related material which may interfer with name resolution – and key ports error. I go into Tools, Options, Connection, and it says I am currently not connected to the .NET Messenger Service. I’ve gone on heaps of websites and tried all the above solutions, I don’t have Norton but I do have Kaspersky. You guys all seem to be really knowledgeable and I’d really appreciate it if you could help me with this. I’ve tried my account on other computers and it works fine – What can I do?

  384. Kelli says:

    I was shut out from Msn for several days.The codes said wireless keyport blocked I didn’t have a clue what that was but…I checked with Msn support as I”m running Vista home premium I looked for a fix. It talked about the time and date needing updating but that was for WinXP only and that was all.There wasn’t anything relating to Vista at all.As they(Time & Date) were correct ,I went into the add/uninstall program and Uninstalled just the live messenger part of the overall program and did a restart.Then I reinstalled Msn and then Msn started to work correctly and I haven’t had a problem today. The other strange part was the other programs relate to Windows Live messenger (mail etc) continued to work correctly. I hope this will be of some help to others as this seems to be affecting different computers differently.

  385. etienne says:

    none of the things you posted worked
    and you write that northon might be blocking it
    well my msn ONLY works if northon IS running, and my northon is expired and i hasn’t been updated for years
    if i turn northon off i can’t sig in
    verry strange, also when i trun northon off i can’t lopg in on sites like “hyves”
    only thing i havn’t tried is registerysmart (which i have installed on the laptop)”
    when i go to msn>tools>options>conection it says: you are currently not conected to .NET Messenger Service
    (if i turn northon on it says something like: you are conected to .NET Messenger Service)
    i can logg on while northon is on, but my northon is installed incomplete becaus ther’s a virus on it, and the way it’s installed now will give errors while booting up my pc but it won’t activate the virus.
    still Northon is making my pc verry slow

    do u have ANY solution for this?

  404. sam says:

    Thx man ur so clever!

  405. cj says:

    just a little hint to those still having problem with msn key port
    open IE -> tool -> advanced tab -> under security, unclick “Check for Server certificate revocation ” -> CLICK APPLY -> click OK -> close IE -> reopen IE again
    be sure to CLICK APPLY then OK
    i found out that the box will be automatically ticked again if u just click OK then OK, NEED TO CLICK APPLY, THEN OK
    and make sure to close the IE, then reopen it

    also, i think norton somehow contributes to this problem, cuz i got this outdated info of it [even tho i did update it], then my msn stopped working !!!!
    when i switched av software to kaspersky, no problem at all so far!!!!

    hope this helps=]

    The following resolved the Messenger/MSN ports error for me on Windows XP:

    1. Start > Run
    2. Type ‘cmd’
    3. Type ‘netsh winsock reset catalog’ then press enter (to reset winsock entries to installation defaults)
    4. Type ‘netsh int ip reset reset.log’ then press enter (to reset tcp/ip stack to installation defaults)

  412. Han says:

    I’ve had this issue before and tried everything I could google up about “Key Ports error code 80048820″. I can only say that if you’re using FreeGate Proxy and/or UltraSurf Proxy and didn’t close the program properly after browsing the web (i.e. through Task Manager or closing IE as you always do by clicking [x]) you will experience this error everytime you try to sign into WLM. And unless you start FreeGate or UltraSurf again and close it PROPERLY this time by right-clicking and exiting on the program icon in the task bar you will get error 80048820 non-stop.

    BTW, if you’re wondering why you have to restart FG/US and closing it not by using the [x] button but instead by right-clicking the icon in the taskbar is because the programes automatically set and remove your proxy settings upon opening/closing them.

  413. Freaky says:

    Hello Everyone out there having this problem!
    I too was hit by this ULTRA-aggravating problem, and just believe me I tried EVERYTHING there was to find about this problem on the internet. Yet it didn’t work still! BUT I found myself THE solution for when all else fails!
    I went looking into the list of services running on windows (vista), and thought if I see something strange IMA CLOSING IT DOWN! and guess what I found, The service of Windows firewall still running while I completely turned it off. so I right clicked, shut it down, and tried to reconnect on messenger… … … … OMG IT LOGGED IN!

    Really that is about what happened to me, i was like FINALLY!

    To look into this list, just press CTRL+ALT+DELETE and select task manager, then look under the tab services.

    After that I normally turned on windows firewall, and I set configuration to default (in configuration of firewall)

    I Ain’t saying that this will work for everybody, but it sure did for me, AFTER I tried All else there is to find.

    Good luck!

  420. I had a same issue but I disable the firewall afterward it resolves.

  421. Jonathan says:

    well unfortunately I have a SOLUTION #9
    1) open control panel
    2) network and internet
    3)turn windows firewall on
    3) click allow program through firewall
    4) add port
    5) name – doesnt matter port- 1863 – TCP
    6) name – Doesnt matter port- 5190 – TCP

    and double check make sure your msn isnt being blocked out in that list it should be checked ..

    This fixed mine and it wasnt a solution up here had a hard time figuring it out on my own I think norton messed mine up tryed to uninstall and never fixed it so I did this.

    It is used for Women’s Basketball (you know, their good basketball team). But it is not good or large enough for any big conference D-1 Men’s team. It’s pretty much an HS gym.

    This jack-ass can apologize from now until hell freezes over but it doesn’t excuse what he said and what he did. The very thought that he could have done this as a “joke” among his friends says more then he’d care to reveal about him AND his friends if he thought they’d find it humorous. He’s also, or should be, well aware of the power of tweets and the Internet and that his absolutely thoughtless and un-civilized comments would be picked up, so I don’t buy his “few seconds” defense of his actions. This is part of who he really is and as always these expressions of deep personal feelings come to the surface in most unexpected circumstances.
