MAC Address

Media Access Control (MAC) address is a unique identifier or a serial number assigned to a network interface. This unique identifier is used in the Media Access Control protocol. It is hard coded in the read only memory of your NIC (network interface card). MAC addresses are used for routing packets between physical devices (i.e. network interface cards) on networks.

SMAC is a nice tool that can help you in spoofing MAC address of your NIC. This tool is available for Windows and works on Windows VISTA, XP, 2003, and 2000 systems. But I am not sure whether it will work on Windows 7 or not. If you are using Windows 7, you can give it a try.
