On two new 2008R2 Servers I noticed an error similar to:

Log Name: Application
Source: Microsoft-Windows-WMI
Date: 1/18/2008 2:37:27 PM
Event ID: 10
Task Category: None
Level: Error
Keywords: Classic
Description: Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.


Doing a little research led me to the MS KB article below where you need to run a small vbs script to correct the issues.

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\subscription")

Set obj1 = objWMIService.Get("__EventFilter.Name='BVTFilter'")

set obj2set = obj1.Associators_("__FilterToConsumerBinding")

set obj3set = obj1.References_("__FilterToConsumerBinding")



For each obj2 in obj2set
                WScript.echo "Deleting the object"
                WScript.echo obj2.GetObjectText_
                obj2.Delete_
next

For each obj3 in obj3set
                WScript.echo "Deleting the object"
                WScript.echo obj3.GetObjectText_
                obj3.Delete_
next

WScript.echo "Deleting the object"
WScript.echo obj1.GetObjectText_
obj1.Delete_
