I did this and got it to work. I didn't do exactly what he did but I used UBCD that is piratically bartPE on steroids. I couldn't load the hives using the run and regedit. That way just displays the content of what is on the running live disk. I did find a regedit(remote) program in the program files that loaded the registry automatically. Went to HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon\ and sure enough it wasn't right. Changed it and rebooted and all was good.
Hope this helps!
