You find high CPU usage for the Wmiprvse.exe process on a terminal server that is running Windows Server 2008 when you run the Windows System Resource Manager

Symptoms

You use the Windows System Resource Manager to manage the CPU usage and the memory usage on a terminal server that is running Windows Server 2008. In this situation, you find that the CPU usage for the Wmiprvse.exe process is higher than expected.

Cause

The Windows System Resource Manager uses Windows Management Instrumentation (WMI) polling queries to check the status for certain key processes, such as the Cluster service. However, these queries consume lots of CPU resources, and the Windows System Resource Manager uses polling intervals of 30 seconds and 60 seconds. As more users log on and as more processes are started, the WMI queries use more and more CPU resources. The query interval that is used when the Accounting feature is enabled can be controlled by a registry value. However, the interval for the Cluster service polling query cannot be adjusted, and this query runs every 60 seconds.

Resolution

You can adjust the interval for the Accounting query by using the PollingInterval registry value. After you apply this following hotfix, you can also change the interval for the Cluster service polling query. You can set the polling intervals to anywhere in the range of one time per second to one time per every 86,400 seconds (1 day). A value of greater than 300 (5 minutes) is recommended only for the ClusterSvcStatusPollInterval registry value and is recommended only when the computer is not a cluster node.
