Hello

I have a W2K server with AD installed. Is there any way I can prevent a user to use more than 30% of the CPU resources ?

Windows automatically shares the available CPU resources among all processes waiting for time based on its own scheme and the priority of the processes.  There is no "quota" system for CPU time.

Why do you care anyway?  If a user is getting 100% it's because nothing else wants to run at that time.

The simple answer to your question is NO.

If you had Data Centre, you could use the Job object to limit certain processes, but this feature is not available in Win2k Server (or advanced server).

One clever trick is to set the priority of the task you want to limit to idle. That way, it will only get CPU time if nothing else is running.

I care because, some of the users are connecting to the server with Terminal Service. If a non TS-user has something to compile or are running another process which are using a lot of CPU resources, the TS clients can't do anything. It lookes like Windows gives much more resources to a process that demands more than other processes. So, if I can't prevent a user to use more than ex. 30% of the CPU resources, the TS-clients still can use there sessions to somethig usefull.

Sadly, only the Data Center version has the job object, and the ability to control the CPU usage of a particular process. I'm not aware of any 3rd party tool that can achieve this.  You can fiddle around with process priorities, but this probably will not achieve what you want.

Sorry.

If the comment given was correct, but not what you actually wanted to hear, can you award the points still.

Unfortunately they are correct and you cannot put CPU usage quotas per user...

Hi Thomas

I have found a 3rd party tool, that probably will help me.

If you want to see it, you can find it here:
