Windows server unable to log in

Recently when trying to access a Windows Server SimpleHelp has like a pre-credential pop-up for logging in. No matter how i enter the credentials, it will not let me in showing the error:

Error authenticating administrative user

Cannot run program C:\ProgramData\……\elev_win.exe

The system cannot find the file specified.

Fortunately I can access the server without the GUI and the file elev_win.exe is not there, but it is available in other folders related to SimpleHelp. I copied one over to the directory, but it’s still nto working. What can I do to fix it?

Restarting the SH remote access service fixed it after having copied that file over.
