Each day, a particular user constantly get locked out of his computer. We always need to unlock his domain account to allow him to log in. I believe he has a session somewhere on another machine, where we need to log him out. This happened after he changed his domain password.
I use a lockout tool to trace the source:
I then check the DC security log, and the client address (highlighted) points to an Exchange server. However, the user would not have access to log into our server. So, I am thinking that maybe he needs to set his new password on a mobile device (cell phone). However, the user mention that he does not use email on his cell. I know the lock out is occuring somewhere within email, but cannot trace exactly where. Anything I can try to resolve this issue?
