Hello, I am having a problem with Windows not reading the GPO history from the registry on many computers. Event ID 1047 from Userenv is logged in the event logs. I have followed instructions according to Microsoft Article 319006 and deleted the History sub keys from the registry as well as deleting any existing profiles from the desktop. The error continues to appear. Does anyone know how to detect and repair this problem on a large scale? I have about 5,000 computers to work with. Thank you, Regards, Cynthia Berridge
