For this post, I copied the netlogon log (%windir%\debug\netlogon.log) to my test workstation (C:\Logs )

netlogon-log-powershell

The issue was that this user changed his password but he left a session (Terminal Server) on a server using his old password.

Terminating the session resolved the issue.
