Let me get your thoughts on terminal server performance problems. The server hosts average 25 users which, after running some numbers, on average use 600MB memory with their main applications running (web browser, adobe reader, IP phone client). All users are on the same LAN as server. We constantly experience slow response and short session lockups. Combined CPU usage is on average 10%. What appears strange to me is that the system shows 29GB physical memory with 25GB of it free. The page file usage is about 50% averaging 9GB used.

Some server specs

OS: Server 2003 32bit Enterprise with /PAE flag RAM: 32GB CPU: 2xQuad Core @ 2.27Ghz HD: RAID5 1.2GB

After doing basic troubleshooting using performance monitor it leads me to believe that the performance problems are caused by the 32bit OS limitation in addressing full 32GB of physical memory even though the /PAE flag is used.

Can anyone suggest something, troubleshooting steps that can lead to a more conclusive answer?

Thanks
