I'm having a very strange experience with Server 2K8R2 after one of my local users deleted his chrome browser. He has been unable to logon with a password (service unavailable) so I suspected his user profile was corrupted. I performed the S-I-5... key routine in regedit with no luck. i can see and access his profile from the admin account and all his files were still there so the next step was to create a new profile and copy the files over. Well, no newly created user can logon. All new users experience the same logon error! I looked for a thread with a similar discussion and couldn't find one, can someone help?
