When you use the at command with Shutdown.exe to schedule a Windows XP-based computer to shut down or restart, the computer does not shut down or restart as expected. When the scheduled shutdown task starts, you may receive the following message in a command-prompt window:
This problem occurs because, by default, tasks scheduled by using the at command are run under the Local System account. Shutdown.exe tries to enable certain rights before it executes the shutdown action. The Local System account does not have one of the rights that Shutdown.exe tries to enable, and therefore the action is unsuccessful.
