We just bought a new server in my office and it's running WinServer 2003. It was running fine, but now the Server doesn't "see" the desktop computers on the network and the visa versa. All the desktop computers are still able to access the Internet through the server, so I'm sure the connection is still there. I've never had to troubleshoot a problem like this, so I'm not really sure where to begin at all. What settings can I check? Any help would be appreciated.
