Server Manager 2016 : Configuration refresh failed with the following error: Invalid class

 

server manager :manageability :data retrieval failure occurred

the SERVER MANAGER DASHBOARD had a red flag indicating the REFRESH FAILED.  When I clicked MORE I saw :

 Configuration refresh failed with the following error: Invalid class

 solution : Refresh .MOFs:

1. Launch a CMD PROMPT (ADMIN)  – make sure it is as an Admin       
2. type :      cd C:\Windows\System32\wbem\AutoRecover                            
3. type    :     for /f %s in (‘dir /b *.mof *.mfl’) do mofcomp %s
4. Launch your SERVER MANAGER and let it take the minute or two it needs to start up.

That’s it!
