Issues with Switching Non-Admin Domain Account on a Windows Collector

I stumbled upon this issue recently.

The script had already run successfully on Windows Server and was monitored with a non-admin domain account.
After an update, one service couldn't be queried and the non-admin script would fail with the following message:

Error occurred: Unexpected error
Error occurred in GetSecurityDescriptor step. Kindly retry or do the setup manually.

In our case, a simple WMI repository reset did the trick: 

Stop-Service Winmgmt -Force
winmgmt /resetrepository
Start-Service Winmgmt

Upon rebuilding the repository, the script ran without issues
