RE: Memory usage with Win Terminal server

Tech-Archive recommends: Speed Up your PC by fixing your registry

In that case I'd look at ThreadMaster which is free, and should be pretty
easy to configure.

Don't know. I worked with a DOS based Database Application (R:Base) that ran
from a network share from both 2000 and 2003 terminal servers that had the
same problem.

This same problem exists on 2000/XP workstations, except that the excessive
CPU usage doesn't cause a problem because there's only one concurrent user.
Once you apply this to a multi-user environment like terminal server, three
users of an application consuming 30-50% CPU can cause a huge problem.

I'd try threadmaster first, because it's absolutely free. Applications like
Autema Armtech and Provision Networks Max-IT work on a fair share system,
i.e. dividing the CPUs like a pie between users, to prevent one user from
using more than their fair share of CPU time, if others are requesting CPU
time. If there are no other CPU requests, one user will be allowed access to
the entire amount.

I don't know of any native way to resolve your problem, unless you're using
Enterprise Edition, which inlcudes WSRM. The apps I recommended are far less
expensive and feature rich than upgrading to EE ro use WSRM (WIndows System
Resource Manager).

Could this be caused by the DOS application being on a separate machine from
the Terminal server to which they are connected. This application has worked
for years until I changed Terminal server operating systems

When using a DOS application on any Terminal Server, whether NT4 TSE, 2000 or
2003, you should look at using a CPU management program like Aurema Armtech,
WM Software Relevos, Threadmaster... as a few instances can easilly dominate
the CPUs due to constant keyboard polling by the DOS app.

TameDOS exists, but I'm not a fan of using such a DOS specific program, when
I can purchase a product that addresses all processes.

I have a similar CPU utilization problem. I recently moved to 2003 Termial
Services from 2000. Since I moved the CPU Utilization has been a t 100%. The
users are emoting in to use a dos application on a 2000 server. Whe I open
task manager on the terminal server machine each user has opened the 'NTVDM
executable' I am only able to get 3 to 4 users in when on the 200 server I
had 12 users up at all times.

Any ideas would help

I'll check, otherwise I have to do the same googling you did.

Thanks Patrick - was there a solution for this problem

We have 2 Windoes 2003 servers. In one of the servers there were some
services that did not loaded when booted up. After investigating on the
Events
Log, it was found to be run out of resources and memory, thus causing some
required services not be loaded properly. A second look at the memory
utilization, it was found to be OK. But the CPU utilization for both
processors were 100% at all time. After checking on all the processes, it
was found to be the wmiprvse.exe of Windows Management Instrumentation had
held up all the CPU power. It was also found from Internet that it was a
known issue that caused memory leak when calling on Terminal Services on
W2K3 servers. Does any one have a solution for this/
