the group policy client service failed the logon

- Restart the computer.
- Login with an administrative account (not the account that is having the problem).
- Rename the ntuser.dat file (to something like ntuser.old1) for the user that is having the problem (C:\Users\%username%\ntuser.dat).
- Log off and login with the user account, a temporary profile should be created.
- Log off and login with the previous administrative account.
- Open REGEDIT and go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
There should be a profile under that key that has .bak after the SID number (e.g. S-1-5-21-245852018-2450494779-245611912-1000.bak).
- Select the key and check the ProfileImagePath string value relates to the correct user then delete the SID key (that ends with .bak).
- Restart and login with the affected user account, they should be able to login now.
