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 msn.com 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 MSN.com or hotmail.com 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

  6. Andrew says:

    i tried all of the above at home and non seemed to work, so i brought it to another wifi hotspot (my work) and everything seems to work perfect so i think it’s the wireless router or something to do with the service provider?!

    Hope this helps??

  10. 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)

    Recommend against Solution 9.
    Registry Fox is reported spyware and blacklisted on the WOT (Web of Trust).

    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.

    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!
    Your friend Rik (Freaky)

    Adding from me,

    Maybe it because of ur Antivirus Program.

    U can disabled itu then sign in.
    After that, enabled again di antivirus program.

    It maybe because the program protected ur computer to sending important data.
