I have installed Microsoft Live Communications Server 2005 on my network. I cannot get any clients (Office Communicator or Windows Messenger 5.1) to connect to the LCS Server. All of the services are running and everything seems to be ok from the server end. I've checked a couple of the diag tools and the server seems to be responding ok. I do get this message when using LCSDiag.exe with the test client:
504 Server time-out
The signing failed. There is a connectivity problem on one server
Please go to server servername.domain.local and run LC Diagnostics
to check server connectivity to all server from WMI
if the test passed go to the next server in the chain and run the test again.
I am using TCP, not TLS. I know TLS is more secure but for simplicity, let's make TCP work.
Anyone have any ideas? Everything seemed to be OK during the install, but I cannot connect at all. Thanks!
