Windows was unable to read the Windows Management Instrumentation (WMI) filter information associated with the Group Policy object %8.This may be caused by a deleted WMI Filter defined in the domain that is still in use by Group Policy objects. Group Policy settings for this Group Policy object will not be enforced. Other Group Policy objects may still apply. Windows will attempt to retrieve this information at the next policy cycle. This specific problem may be resolved by identifying all GPOs that reference the WMI filter and removing the references. Contact an administrator if this event recurs for several hours.
