Question : I cannot authenticate to a Windows 2003 server on the network

I have a Windows 2003 server that does not allow me to logon to it on the domain. I can only logon to the computer. Users cannot authenticate to the server. It runs Microsoft Communicator 2007. The Communicator services are not strating because the system cannot authenticate to the network.
