Event Log Error: Event Source:WinMgmt Event ID:10

I am getting the below error on event log on Windows Server 2003 every few minutes:

Event Type: Error
Event Source: WinMgmt
Event Category: None
Event ID: 10
Date: 2/28/2007
Time: 12:50:48 PM
User: N/A
Computer: POST-GATEWAY
Description:
Event filter with query "SELECT * FROM __InstanceDeletionEvent WITHIN 600 WHERE TargetInstance isa "Win32_PnPEntity"" could not be (re)activated in namespace "//./root/CIMV2" because of error 0x8004106c. Events may not be delivered through this filter until the problem is corrected.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Any ideas how to fix this thing?
