Consider the following scenario:
You run a script that calls the DefragAnalysis method of the Win32_Volume WMI Class on a computer that is running Windows Server 2003. This script runs on a passive cluster node.
You cannot access the disk resources on the passive cluster node. This lack of access causes the script to fail.
You try to fail over the disk resources to the passive cluster node after the script fails.
In this scenario, the failover fails.
This problem occurs because the WMI Provider Host (Wmiprvse.exe) process that hosts the Vdswmi.dll module leaks a handle in the scenario that is mentioned in the "Symptoms" section. The handle leak prevents the failover of the disk resources.

Terminate the Wmiprvse.exe process that hosts the Vdswmi.dll module. To identify the process ID of the Wmiprvse.exe process that is hosting the Vdswmi.dll module, run the following command:
