Virtual PC setting - resetting MAC address.
In the case where you would want to change the IP address by forcing the DHCP to re-assign a new IP to you Virtual PC. (or in the case you are using the same *.vmc file and you don’t bother to recreate a new one) Stop your virtual machine. Then, in your *.vmc, look for <ethernet_card_address type="bytes">0003FFxxxxxx</ethernet_card_address> Remove the number so the line appears as follows: <ethernet_card_address type="bytes"></ethernet_card_address> After you remove the number, Virtual PC will create a new MAC address the next time you start the virtual machine. And in turn, DHCP will assign u a new IP address for your virtual machine.
