Wake on LAN Tool
Wake on LAN (WOL) is a very useful technique that that would help you switch on a computer in your corporate network.While trying to troubleshoot a particular computer, you may need to wake powered-off computers to kick-start your troubleshooting process. Walking up to the device every time might not be practically possible always. In such cases, WOL comes in handy; you can instantly wake computers in your local network.
Wake On LAN process involves sending a broadcast message (magic packet), that has the MAC address of the target machine, within a subnetwork. So that, in turn the target computer whose Network Card is running receives and verifies that the message is for itself and boots up the computer.
