The User Profile Service Failed The Sign-In. User Profile Cannot Be Loaded – Server 2012

While working on server 2012, someone messed with profiles folder and so nobody was able to login on server. Whenever we try to login on server we got this error:

The User Profile Service service failed the sign-in. User profile cannot be loaded.

The solution worked for us:

  1. Try to access the server from another server as file shre to C$ and freeup some space to see if its a problem of disk space. If no success then proceed to step 2.
  2. Go to Computer management on another server and connect to problematic server management from Actions menu. Check the event Logs and you must find an entry in Application logs as:

Now, Make the local system account an owner of the v15 sub directory listed in the above error, and then apply to all child sub directories and files and then Enable inheritance on the V15 sub directory, and then delete all non inherited permissions on V15 and it’s child sub directories and files.

If the problem still remains same then continue the troubleshooting steps:

3. Delete all the profiles from REGEDIT ( HKLMSOFTWAREMicrosoftWindows NTCurrent VersionProfileList) EXCEPT for the system related ones.

Thats all. It should normally fix the problem. If not, then post your results in comment and we would like to assist you.
