Hi all, I have an LCS 2005 Server that is running SIP communications in our office for about 20 users over TCP connections. All of the users are using Windows Messenger 5.1 for connectivity to the LCS.
Everything was working just fine on it until the middle of last week, when I added a user with Messenger on Mac (our first one) to the fold. The user on the Mac was connects in just fine to the LCS. However, ever since he has started using LCS and Messenger on Mac, many users, myself included are finding that we can sign-in just fine to the LCS, but all of our contacts show as offline and are showing their full SIP addresses, not the shortened names they usually show when they are online. Also, if we attempt to initiate a conversation with a user, it simply opens up a new e-mail within Outlook. However, the users that are lucky enough not to be affected can see myself and the other affected users online just fine, and they can initiate messaging with us, and once they do, we can carry SIP communications back and forth, as long as we keep the conversation window open.
What's even stranger is that, there is no common thread (that I can tell) between those that have the problems, and those that do not. I've tried reinstalling Messenger, I've tried restarting both services and the Server that hosts our LCS SIP service, to no avail.
Any help on this would be GREATLY appreciated. Thanks!
