"Repair WMI" deletes Bitlocker WMI Namespace - ID: 3400624
We experience the same on many more windows 7 ultimate clients where we run a wmirepair, as described in ID 3400624. After running 'winmgmt /resetrepository' bitlocker works again. We experienced that the SCCM client stops working after this. So we ran another wmirepair and now bitlocker and sccm seem to work properly.
I opened another 'artifact' because the other was closed and I was not sure if a comment would reach you.
