Description

I encountered a problem with a workstation failing to log on its normal user. This error was spontaneous and I could not isolate the cause. I found this to be a problem that microsoft recognizes and they have a fix for it. Here is what I did to fix this problem.

Boot into Safe Mode

  • Reboot Windows and keep pressing F8 during the boot up sequence.
  • Once the boot selection menu appears, select Safe Mode.

Backup the Registry

  • Press [Win] + R to open a run prompt.
  • Enter regedit and click Ok.
  • Click on File -> Export and select a path to save the registry backup, then click Ok

Fix Corrupt User Profile

  • While still in regedit, navigate to HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/ProfileList
  • Next locate the corrupt account folder that begins with S-1-5 using the ProfileImagePath key.
  • Once the account folder has been located, there should be a second account folder with the same name, but with .bak at the end. Replace original account folder with the .bak.
    1. Right-click on the original folder account and select Rename, adding .ba to the end of the name.
    2. Right-click on the .bak folder account and select Rename, removing the .bak from the end of the name.
    3. Right-click on the .ba folder account and select Rename, replacing .ba to .bak
  • Reboot the workstation back into the normal environment.
