Setting CPU Priority on NT/Citrix?

Broue Master asks: "I was recently faced with the task of finding a way to prevent some users from taking 100% cpu time in Citrix. I'm no MS certified anything (but I am a Citrix certified admin) and I couldn't find a built in way to do this. After someone on the NTSysAdmin List suggested trying to set the CPU priority to low from the command line, I investigated and found a small freeware that did the trick: PrioSet. I don't have a big user base: 3 power users (who are my problem with their Access and Excel use) and 10 regular users (and the people most affected by the problem). I'd like to know if any of you have previously tried this software, or if you've run into the particular problem when one user is getting 99% of the CPU for a long time while all other users only share the spare 1%. Did the software solve the problem or did you solve the situation by other means?"

If the problem is 16 bit DOS apps, Tame can help.

Also, when you installed Office, did you run the appropriate app-tuning script afterward? (Search in x:\wtsrv for *.cmd and you'll find a whole bunch of them.) These scripts can make a big difference with certain versions of Windows.

You might also try the MetaFrame Installation and Tuning Tips. You might find a more recent version if you dig around.

Actually, if he's running Win2k server, he can use the Job Object API
This API allows you to set per-process limits on cpu, memory, user mode execution time, min/max working set, processor affinity, thread priority, UI restrictions, and security restrictions.
I believe that Win2k Datacenter Server comes with a Job Object MMC for creating Job Objects / adding processes to a Job Object.
