network problem terminal server?

[RO|_F]

Hello,

I am trying to pin-point the performance problems we have with our windows
2003 sp1 terminal servers (rdp)
Problems that we have are:
- freezing screens
- long response times when click on open file (e.g. in Excel)
- problems with loading and unloading profiles:

Windows cannot log you on because your profile cannot be loaded.
DETAIL - Insufficient system resources exist to complete the requested
service.
Windows cannot unload your registry file. The memory used by the registry
has not been freed.
DETAIL - Insufficient system resources exist to complete the requested
service.

When I was employed in the company I work for, I noticed that
- instead of using a router all rdp servers are equiped with double network
interface cards, each one acting on a different network (192.168.x.x and
10.46.x.x). On both networks users connect via rdp.

I started tracing with performance counters.
What I would like to ask is this
- how can I prove that double network on one machine causes problems? What
counters should show this?
- situation seems to get worse, though they always used to work this way.
What can be checked more?
(I checked (and improved) disk performance, fragmentation, folder
redirection, disk space, page file location and fixed size, updates and
patches on applications that run (system were never patched before)

Thanks for any help.

Best regards,

Rolf

Hi Rolf,

1. How much physical memory does the TS server have?
2. How large is the swap file? If I remember correctly this should be
approx. 2.5 times the physical memory for a TS.
3. How many concurent users is the TS serving?
4. What is the latency between the clients and server?
5. What is the average cpu load of the TS during normal operation?
6. During normal operation, do you see a lot of disconnected (but running)
connections?
7. Are you providing any other services (DC, etc) with the TS boxes other
than Terminal Services?
