The Paessler WMI Tester is returning error 80041010 specified class in not valid when I try to access a Windows HyperV Server in a workgroup. I am able to use powershell from the same system as the tester, and I get a reply. The tester is version 2.3.2.6.

Every issue I've had with WMI queries have been credentials related. When I change the device from inherit to a specific administrator account then test, it starts to work. I then change it back to inherit and it continues to work. It's like it looses it's inherited qualifications.

Are you still getting the error with the tester even now that it's working in PRTG?

I am running the query 'SELECT * FROM Win32_OperatingSystem' in both the Tester and PowerShell. The credentials for both methods are Server\Administrator.
In PRTG I tried to enter the credentials on the device directly and got the same error.
Powershell is working, PRTG and the Tester are not.

Have you tried to re-register the classes as recommended here:

What query are you trying to run with the test and what credentials are you using? Also, what query are you using with Powershell?
