Mac?

Note: to check your MAC address easily under Windows NT4, Windows 2000 or Windows XP: Click "Start", choose "Run...", type CMD and click OK, then type ipconfig /all in the Command Prompt window that appears. The number under physical address is the MAC address. If multiple IP are displayed, you should look under the label "Ethernet adapter x", where x is the name of your connection (which is Local Area Connection by default). In Windows XP, you can also type getmac to retrieve the mac addresses from installed hardware, connected to your machine.
