SCOM2012 SP1: Operations Manager failed to run a WMI query

Hi,

how can I solve this issue:

OS: Windows2008R2SP1

Object enumeration failed


Query: 'SELECT DisplayName, Name, StartMode FROM Win32_Service WHERE Name="ClusSvc" and StartMode!="Disabled"'


HRESULT: 0x800700a4

Details: No more threads can be created in the system.



One or more workflows were affected by this.
