I have a client with a similar problem. He's running a terminal server for serveral remote sites. He uses Win2K as the terminal server which accesses the main server. The terminal server uses a 1 Gig processer and has tons of memory. Users accessing the main server never have any problem but the remote users find that the terminal server bogs down after about a half a day of service.

His temporary solution: The terminal server is rebooted twice a day, at 5 AM and at noon (when everbody knows to get out).

His (hopefully) final solution: A dual processor was ordered as he feels that this is the problem.

Good Luck
