I have a Windows 2003 SP2 server that I use as a terminal server for about 18 people. The server is a Dell Poweredge 2800 dual 3.0 gig Xenon, 8 gig ram, RAID 5 configured with 4 15K SCSI drives (3 for the array and a hot spare).
The server is running as a straight "Workgroup" server with no AD.
They use Microsoft office 2003 and a custom written .Net/ Access/VB/SQL program but the SQL is located on its own server.
The issue I’m having is slowness. The terminals seem to just hang as if locked up then start working again. When I look at the processes, the machine doesn’t seem to be working very hard with the processors loping along at just over 50%. When I look at PERFMON the green line (Avg. Disk Queue Length) is slammed to the top and the blue line (pages/sec) is mostly pegged to the top with a few bounces up and down in between.
Not sure what to check or how to find out what processes or users are using that much disk resource. Do any of you guys have any suggestions on how to troubleshoot this issue? I’m open to almost anything at this point.
