Right click the LAN icon, click the Configure button under the NIC, click
the Advanced tab and then look for "Managed Address" or "Network Address"
and enter a new MAC address.

.... you've just changed the MAC address that the network will see.

Ethernet cards have a permanent address that cannot be changed. They also
have
a software address that can be set in the registry. Both can be queried by
IOCTL on NT4 and later.

If you find a way to change the permanent NIC address, you can also find a
way
to change disk serial numbers.
