Everyone's MSN Messenger signs off at the same time frequently.

[ohif]

All the PC's on my windows 2000 domain sign out of MSN at least once every hour and a half at the same time. When they get signed out internet explorer is still working fine. They can sign in right away but it is really annoying. I dont have any restrictions in my router I've double checked that. I can't find anything restricting it on my server, and I've contacted my ISP and they don't have anything stopping it. I don't understand its like its timing out after a certain time and restarts everyone. Has anyone had the same troubles or any help?

Thanks!

Does anyone have a different IM (like Yahoo?), and if so, does it experience the same problem?

If something was sucking up all of your network bandwidth for just long enough to disconnect the IM clients and no longer, it would be very difficult to use IE at the same time to see if that was also down; by the time you launched the browser or went to your home page, it would be back up.

From a software perspective, I would give a hard look at all of the client machines (if that's possible) to see if maybe one of them had a virus or spyware that was periodically spewing a bunch of garbage out to the internet and using all up your bandwidth. For instance, as people leave and shut off their machines, does the problem go away? You can easily check how many packets a machine is sending out and receiving, if one of them is totally out of whack, that may be the one.

Hardware-wise, if you have a cheap or old firewall, I've seen them go nuts and do stuff like that (flicker out for a second). Low end routers and hubs are also likely suspects.

Hope this helps!
