I have a scheduled task on a Windows 2000 Server that doesn't start. It was working when we had our LAN set with a Workgroup, but we changed to a domain and we're getting this error now:

The attempt to log on to the account associated with the task failed, therefore, the task did not run. The specific error is :
0x8007052e : Logon failure : Unknown user name or bad password.
Verify that the task's Run-as name and password are valid and try again.

Anyone got an idea?
