Just installed a Standard Edition 2007 OCS and it sort of works :-( Instant Messaging works, automated logins work, but Live Meetings fail. I am able to schedule and join Live Meetings, but never the same session (Atendees always = 1). In other words if I start a Live Meeting with Copmmunicator, the Live Meeting clients join seperate Live Meeting Sessions. The same thing happens when I use a Meeting ID or Entry Code with live meeting.
When I run the server Validation tool it all passes except the Front-End Server Validation which fails on "Check two-party IM" "Attempting to establish SIP dialog: Processing failed as one or more steps did not complete successfully" (Failure [0xC3FC200D] One or more errors were detected ). Which is weird because Office Communicator seems to be working fine and Live Meeting is the problem.
My Demo/proof of concept OCS worked fine....the demo OCS was installed in a sandbox single tree, single domain AD environment. The production AD OCS is installed in now is a resource domain and there is a Root AD domain above it....
