i tried to connect windows messenger 5.1. but this following error: Signing in to SIP Communications Service failed because the sign-in name, username, or password is incorrect, or the authentication service is not compatible with this version of the program. If you have signed in correctly and the problem persists, contact your network administrator windows messenger 5.1's connection tab missing. how to enable connection tab?

This is not really the right forum to post this kind of question. I will find a more suitable forum, and move this thread there.Kevin Remde US IT Evangelism - Microsoft Corporation http://blogs.technet.com/kevinremde
