Could anyone please help me!

I have a batch file on NT 4.00 server. It backups files from another server via this file.

However I get the following error in the log file

Backup started on 2/16/05 at 1:48:44.

Backup completed on 2/16/05 at 1:48:54.
Backed up 0 files in 0 directories.
Processed 0 bytes in 10 seconds.


When I run the batch file, there isn't problem. However, when I schedule the batch file that is when the problem occurs. I know that it is the permissions.

I can't change the right in the task scheduler service since "the system account and this account" radio button is locked. system logon was selected.

I have another Windows NT4 Server which I can set the system account, I believe someone has installed IE5 and that has changed the scheduler service.

How can I change the system account? or is there any solution for resolving this sitution?

Many Thank in Advance!
