[Tutorial] How To Turn Off Or Restart A Remote Computer
Windows has a shutdown.exe which is a small utility that you can use to shut down or reboot a remote Windows computer that is in your LAN. At first, you must configure Windows computers that you want to turn off or restart remotely to accept a remote connection from your LAN. This requires the activation of the Remote Registry service and the authorization of the passage through the firewall built into Windows. Once done, a simple command will allow you to turn off or restart a computer on your LAN directly from your Windows computer.
