Windows XP backup not working in Windows Server 2003 Environment

Hello All,

I've been trying to backup my windows xp box to a network drive in a
2003 domain. The error that i've been constantly getting in the
Scheduled Tasks Log is:


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.


The xp box is mapped to a server. I created the backups with
Administrator Rights, so i don't believe rights should be a problem.
Can someone help me with this situation? Any information is helpful.


Thanks!
