Bug #894
Updated by Daniel Curtis almost 7 years ago
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. h2. Boot into Safe Mode * Reboot Windows and keep pressing F8 during the boot up sequence. * Once the boot selection menu appears, select *Safe Mode*. h2. 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* h2. 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*. *# Right-click on the original folder account and select Rename, adding *.ba* to the end of the name. *# Right-click on the *.bak* folder account and select Rename, removing the .bak from the end of the name. *# #* Right-click on the *.ba* folder account and select Rename, replacing *.ba* to *.bak* * Reboot the workstation back into the normal environment. h2.
