I have built a test domain to create a Live 2005 server. I have run LCSdiag.exe and am confident that the server is working normally. After installing Windows Messenger 5.1 on a test client system, I am trying to configure the SIP settings. On the Accounts Tab, only .NET Passport Accoun and Exchange Account are present. There is no SIP Communications Service Account option at all.
I think this may be because I had Communicator client installed on this system, but I have removed it. On another system without Communicator installed, and using the same install file, I do get the SIP options.
Does anyone know if Communicator is the reason, and if so, how to I remove Communicator completely to allow Messenger to have the SIP option?
