The Reboot Computer action causes a computer to reboot or shutdown when it is run. You can specify which computer using the radio button options. By default the monitored computer will be rebooted when this action is run.
To shut down the local computer, the user that is running the service must have the SE_SHUTDOWN_NAME privilege (also known as the "Shut down the system" policy). To shut down a remote computer, the user must have the SE_REMOTE_SHUTDOWN_NAME privilege on the remote computer.
