Win2003 Scheduled Tasks 0x80070005 Error

Trying to setup a backup job (kicked off by a .cmd file) on Windows 2003. I have a special, limited rights, user account created (rather then running the backup job under the administrator account). Everything seems fine until I go to test my scheduled task.

Looking at the log (Scheduled Tasks - Advanced - View Log) will show:

Unable to start task.
The specific error is:
0x80070005: Access is denied.

"Access is denied" error message when you run a batch job on a Windows Server 2003-based computer

As expected, this is a permissions error. Specifically, you need to grant permissions for batch processes to use "cmd.exe".
