The MAC address is unique to each nic, they can't be changed. This MAC address is hard coded to the individual nic card, there is no two in the world with the same address. The only way to change the MAC is to physically change the card, but you would still have no control over what address you get.How to change mac address in vista ?
You cannot change the MAC address. It is hard coded onto the Network Interface Card.
Change Your Mac IP Address Manually


Step 1 Select the network configuration that has the green dot next to it, from the ';TCP/IP'; screen you opened before. This is your active connection and will probably be the ';Built-In-Ethernet'; option in the drop-down box. Then click the ';Configure'; button at the bottom of the dialog box.





Step 2 Click the ';Configure IPV4'; drop down menu next and choose ';Manually.';





Step 3 Type in your new IP address in the box under the TCP/IP menu. Simply delete the number that is in there and enter your new one.





Step 4 Click ';Save.'; Your address has now been changed.

You can't have 2 devices on a LAN with the same MAC address. As another poster told, you can use a mask to advertise a different MAC address in Windows, but it will cause issues to have 2 computers with the same MAC on the same LAN and not work.
