I have 2 Windows 2000 servers in a domain 'DC', which run numerous windows scheduled tasks under the 'DC\Task-User' account. These tasks are and have been running successfully in the past couple of years without any account/password modifications. Yesterday, the tasks went to 'Could not start' status. Myself having an admin account, was able to run these tasks with my credentials. Today, I ran the tasks again under the DC\Task-User account and they seem to be running fine without any issues. This has happened in the past too. I'm not into networking so don't know much about the underlying problem. Has this something to do with a Domain controller account authentication? Any pointers will be great!
