We are experiencing a problem with a Windows Server 2003 machine, this machine runs Terminal Services, and users log on to use an accounting package which has its data and programs stored on a file share on a Windows Server 2008 box.
Intermittently, the terminal server will "lose contact" with the file server, i.e. will not be pingable from the 2003 machine, by host or IP. When this occurs, the 2008 machine remains accessible from other machines on the network, also, the connection on the 2003 machine is still very much active.
To diagnose the problem, or at least get an idea of the frequency of the problem I have set a ping x.x.x.x -t to the 2008 machine to watch for examples of it going down. However, while this is running, the problem doesn't occur.
There's no event log entries that pertain to the problem on either machine.
Any ideas on why this is occuring?
