I have over 150 PCs with this error. 

WMI repository corrupted

Corrupted WMI repository can cause this error, follow the steps mentioned below to re-build the WMI repository;

  1. Go to Start > Run >
  2. type rundll32 wbemupgd to upgrade the repository, (this will happen at the back end and no changes will be notified in the UI)
  3. Go to Run and type services.msc
  4. Select Windows Management Instrumentation service
  5. Stop the Windows Management Instrumentation service.
  6. Then, go to the %Windir%\system32\wbem  folder
  7. rename the Repository folder
  8. Start Windows Management Instrumentation service.
  9. Now, download the assetscanlock.txt and rename it as .vbs
  10. Now, run the assetscanlock.vbs file and then initiate the inventory scan.

it is required to do steps 1-8 manually on 150+ PCs? same with WMI Diagnosis utility? This can't be automated?
