  1. Your “colleague” is an idiot or is the cause of this problem. Even if you clear the logs you save them first. This is standard procedure.

    If this is a member server unjoin it from the domain to a work group, delete the machine account from AD and then add it back again to the domain.

    Let’s see if that will re-establish the domain communication.

    I would also request you post a ipconfig /all from the server for review.
