Replaced Server 2000 with new Server with Server 2008 in 2009. Server 2000 was left as Terminal Services Server and file storage. This summer Server 2000 lost half its memory so replaced it with a used Server (but reformated) with Server 2003. Server 2003 became the Terminal Services Server and file storage. When Server 2000 is disconnected the network is very slow. Opening a file on Server 2003 or 2008, from a workstation, takes seconds with Server 2000 disconnected, immediate when connected. Another issue is that any workstation with Win7 takes minutes to show desktop after entering password. The desktop is black for several minutes altrhough you can see the cursor and move it.
I must have missed a step some where.
Any suggestions would be appreciated.
