Managment tools may require WMI Namespace to be recreated after SP3 update
If you use the management tools that are dependent upon WMI (such as posdm.exe), the WMI namespaces may need to be recreated after significant OS updates (such as applying SP3). A temporary fix, can be done by choosing the repair option from the installer; however, the recommended fix, in order to avoid future reoccurrences, is to use mofcomp as described in the attached document.
