When you try to add a host to System Center Virtual Machine Manager 2008, it fails with the following message:

Error (2912)
An internal error has occurred trying to contact an agent on the server.
 (Unknown error (0xc0000bbf))

Recommended Action
Ensure the agent is installed and running. Ensure the WS-Management service is installed and running, then restart the agent.

In the Application log on the host machine that you’re trying to add, the following events may be logged:

WMI, Event 10
Event filter with query "select * from __instancemodificationevent within 30 where targetinstance isa 'Win32_PerfFormattedData_PerfDisk_LogicalDisk' and targetinstance.PercentFreeSpace < 1 and targetinstance.Name != '_Total'" could not be reactivated in namespace "//./root/CIMV2" because of error 0xc0000bbf. Events cannot be delivered through this filter until the problem is corrected.

WMI, Event 5612:
Windows Management Instrumentation has stopped WMIPRVSE.EXE because a quota reached a warning value. Quota: HandleCount  Value: 12853 Maximum value: 12288 WMIPRVSE PID: 7232



This issue occurs when the performance counters are corrupt on the host you are trying to add.


Perform the steps documented in the following knowledge base article to manually rebuild the performance counters:
