I tried both options described at the site. First I ran Dial a Fix from a normal login and it ran through its paces, but the problems remain. A side effect was that only my own user ID appers to be available.
Then I ran the !RUNME.bat (from Repair Permissions.zip), from the command prompt in Safe mode. It ran through, giving errors at each stage and the problem still persists.
When I run Regedit, the keys are generally locked so that I cannot even open them.
Can you suggest what I should try next? Would the security logs be of any assistance? I've included them just in case.
Also, how can I restore the other logons? (When I try to add them back in I am told they already exist, so it looks like they are just hidden.)
