I am using Windows 7. I have the same error. I never logged on to a domain though. There are no entries in the profile list that I can identify as users. I have two "Default" listings. I previously deleted the ntuser.dat file and then recovered it from the recycle bin, but I was being told that I was signed on with a temporary profile. Windows did a repair after I tried to load a Registry BU. (I think the BU was for a different version of Windows) I can log on with the "Administrator" account, but my other account gives my the Group Policy Client Services error.
