I have just implemented Exchange Instant Messaging, everything is working fine except for a few machines. What is happing is they are being disconnected and most cannot reconnect unless they reboot. One person cannot reconnect at all after he gets disconnected from Instant Messaging. The error message everyone that has this problem gets is "Signing in to Microsoft Exchange Instant Messaging failed because of a problem connecting to the service." has anyone else seen this error? I can't seem to find any information about this in any Microsoft Resource. They can all connect to the Exchange server without any problems at all.

Any help is appreciated.

No they are not using both. I don't think I mentioned this before, but the people that seem to be having a problem are on Windows 2000 Pro.

Did you create your _rvp record in DNS for IM ? I have seen this happening when this is not present: Q266643, under Configuring IM, section 2.

If you have done so or if you are going to; make sure you are running ipconfig/registerdns again at theclients

cd..

Tried that several times. I actually have found the solution to this issue to be to uninstall and reinstall the TCP/IP stack. I guess there is some sort of corruption or something that is causing this. Thanks for the suggestions anyway.
