Task Scheduler

[bob]

I recently inherited a pc with Win 2k installed. I have some tasks
that are scheduled to run overnight, but there is a task that has been
"left over" from the previous owner. When I look in the
"SchedLgU.txt" file, I receive the following error message...

"{6923881E-3D99-469B-
B599-8AA1F5AED906}_*********_***************.job" (MOBSYNC.EXE)
12/12/2007 9:00:00 AM ** ERROR **
The attempt to retrieve account information for the specified task
failed; therefore, the task did not run. Either an error occurred, or
no account information existed for the task.
The specific error is:
0x8004130f: No account information could be found in the Task
Scheduler security database for the task indicated.
"{3B3C7F61-2C7A-495F-
B859-5CED223E974E}_*********_***************.job" (MOBSYNC.EXE)

Scheduler security database for the task indicated.

( I have placed asterisk over the previous owners name.) I would like
to delete this task, but it does not exist in the scheduler nor does
the old account exist. Any help would be greatly appreciated.

Thanks.
