I'm having a bizzare problem with a client losing the connection to the server. I have a simple LAN with a single Netware 6.5 SP3 server with about 25 clients. Only one of these clients, running Windows 2003 Server (SP1) with Client 4.91 SP2 (acting as Terminal Server) loses the connection to the server typically over the weekend. All would be well for a couple of days and than the users call to report that they cannot login.
When this happens, trying to login returns a "Tree or server not found" error. The only way to get things back to normal is to reboot the client. I have tried uninsalling the NetWare Client and reinstalling the latest version, doing a "Repair local DR database" on the NetWare server but the problem persists.
As I said, the only client computer on the LAN experiencing this problem is the Terminal Server. Pinging the NetWare server when the problem occurs works fine. All was well for a couple of years now, the only thing I can recall doing on the client was installing Microsoft updates. I am trying to avoid having to rebuild it, so if anyone has any suggestions it would be most welcome.
