Windows Server 2008 R2 may encounter a workaround for a task schedule that cannot be run automatically

Recently met a strange phenomenon, in doing a regular backup of a system to use the non-system with the rsync command, but the manual start is no problem, but also very much expect the bulk of the host on many, how to do? Under Windows Server 2003, there is no problem performing a scheduled task, and there is an unexpected exception under Windows Server 2008 R2.

Under normal circumstances, our mission plan will have feedback values that allow us to determine whether the task was scheduled to run correctly last time (detail connection: http://support.microsoft.com/kb/267031/).

Code 0 or 0x0: Operation completed successfully.

Code 1 or 0x1: The function called is incorrect or an unknown function was invoked.

Code 10 or 0xa: the environment is incorrect.

Code 0x8009000f: General access Denied

Figure 1 See the last run result is not 0

Such a non-0 situation indicates that it cannot be accepted.

I see this error message by setting a breakpoint on this batch.
