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 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

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.

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.

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.
