Wake On LAN is a feature on some NIC cards that allow you to boot up your computer via network byte packages sent through your PC. In my NetPinger application I've been working on I've incorporated this feature. You have to find the MAC Address of a given PC, and then with the MAC/Machine Address you'll be able to send the WakeUp. To verify if you have this on your NIC card, turn your PC off, and see if your NIC Card still stays lit up after you shutdown. Once the NetPinger App is finished I'll post the source code on the internet for download.
