Cannot sign into Windows Live Messenger. Please Help!

Tried reinstalling WLM?

Is your IP static or Dynamic on the PC in question?


Try flushing the DNS cache and release/renew the IP.

Open command prompt window as admin
enter ipconfig/all and hit enter - tells you if its static or dynamic as well as your actual IP address
Next enter ipconfig/flushdns, hit enter
It will confirm flushed DNS cache

then ipconfig/release, enter - releases current IP if dynamic
lastly, ipconfig/renew and finally enter again - renews IP address from DHCP client.

 

when you installed windows 7 did you do a upgrade keeping old files or did you do a fresh install?

if you did upgrade keeping files follow this
I should have mentioned about this problem as I had the same thing happen after the repair install, here's how you fix the problem, exit MSN, go to:
Locate the folders below and delete all the files and folders inside them.

* C:\Users\<Windows login name>\Contacts\ (delete all files/folders in here)
* C:\Users\<Windows login name>\AppData\Local\Microsoft\Windows Live Contacts\ (delete all files/folders in here)
* C:/User/Your user name/AppData/Roaming/Microsoft/MSNMessenger/
* C:/Users/Your user name/AppData/Local/Microsoft/WindowsLiveContacts/

and delete the contents of these folders and sign on, or least that's what I think I did, better just backup those files in case I was wrong but I am 90% sure that's all it was.

Just wanted to add this for future reference as I recently reinstalled Windows and had a problem with messenger again and none of the other steps in this thread or most of the internet helped so I really don't want to loose this very important step to fixing this problem that I have spent hours trying to find the solution for.

You need to run the Command Prompt as Administrator, then type in: netsh interface tcp set global autotuninglevel=disabled

Have you tried disabling your firewall for a moment and test if WLM will authenticate and connect?

 

Maybe check your host file for entires obstructing your connection

C:\windows\system 32\drivers\etc\host

Open with notepad

 

Try restarting your PC, you'll never know until you try

Edit: Do you have internet connection when using Internet Explorer?

 

You could of just looked instead of having a potential uncertainty regarding the possibility ragarding my query. I mean a quick windows explorer search and then you could have been like yea or nea instead of still uncertainty regarding my troubleshooting guestimation...lol

 

You could probably try checking the settings of Internet explorer.
1. Start Internet Explorer.
2. Click Internet Options on the Tools menu.
3. Click the Advanced tab.
4. Under Security - Uncheck the Check for Server certificate revocation.
5. Click OK.
6. Exit Internet Explorer
7. Restart

Check if WLM will connect.

Also under Internet Options of IE,
Under Connections, Click Settings and Check "automatically detect settings".
Might be good to update internet explorer thru wu if there are any updates available.

 

Data compression on?

Can you use Internet Connection Sharing from the netbook to the PC and see if it works that way?
Is Windows 7 on the netbook x86 or x64?
