Windows cannot query for the list of Group Policy objects

I started with this showing up on my sql server

The description for Event ID ( 1000 ) in Source ( Userenv ) could not be found. It contains the following insertion string(s): The Group Policy client-side extension Security was passed flags (17) and returned a failure status code of (8)

Then it changed to this
