Help – MSN keeps signing off

Ok i hope i can help you. 🙂
Are you playing music winamp3 during chatting? if so, I suggest u didnt do that cause it’s part of the problem you’re having.
I made a search concerning your problem and it seems to be quite common. So here are a few things i copy-paste for you from the info i found. Good luck.

[font=Verdana,Arial,Helvetica]1. Determine the .NET Messenger Service status. Visit http://messenger.msn.com/Status.aspx.

2. Make sure you are using the latest version of MSN Messenger. To get the latest version of MSN Messenger, visit http://messenger.msn.com. Click “Download Now”.

3. If you are using a third-party firewall, temporarily disable the firewall or reset the firewall configuration for MSN Messenger to “Permit All” or “Allow” type. For more information, in MSN Messenger on the “Help” menu, click “Help Topics”, and then type network in the “For help” on MSN Messenger box.

4. If you are using a router, make sure you have the latest firmware from your router manufacturer. You may also want to add your computer’s local Internet protocol (IP) address to the router’s demilitarized zone (DMZ) setting. For more information, review your router documentation.

5. If you are on a corporate network and are being disconnected from MSN Messenger, your connection settings may be timing out. Ask your system administrator to adjust the corporate Internet sharing solution or the corporate firewall.

6. There are several running applications that are using up the system resources or bandwidth of your machine. I recommend that you:

a. Close other programs and Web applications running.
b. Close the conversation window, then sign out of MSN Messenger. Wait for several minutes, sign in and send instant messages again.

7. There are spyware/adware and other deceptive software that conduct certain activities on your computer without notifying you and getting your permission first. These activities may include displaying pop-up advertisements, changing Web browser settings, and collecting personal information. There are a variety of tools that can detect and remove unwanted software from your computer. Please go to:

You’re welcome. Here’s some more solutions in case you’re still having problems:

[font=Verdana,Arial,Helvetica]
1) If you’re using a third-party firewall (Sygate, ZoneAlarm, Norton, etc.)
set Messenger to “Permit All” or “Allow” type options in the firewall configuration.

2) If you’re using a router, make sure you have the latest firmware from
your router manufacturer. As well, you might try setting your computers local IP into
the routers DMZ setting (see documentation on how to do this).

3) If you see the disconnection problem on a corporate network, the network
may be timing out your settings — in this case, you might want to ask your system
administrator to adjust the corporate internet sharing solution/firewall (if possible).

4) Finally, this can also happen due to a lack of bandwidth. If you have
Kazaa, WinMX, GNUtella or some other file sharing-type application or something else that takes
considerable amounts of bandwidth, you may want to shut it down and see if that helps the
situation (even if you’re using a high speed connection, these applications can use most of the
resources of your connection)[/font]

From an engineers point of view, the server or end-user is terminaling the connection, if its not you (could be virus or outlook) then the server has, The connection between you and MSN peer’s thought loads of line’s, routers and switch’s, any number of them might of closed the connection or the connection between you and msn have gone stale and you will need to re-connect to get the data syncronised again.
