RE: Changing the mac address on Windows 2000 and XP

["Joe Osborn" <joe.osborn () codejock com>]

Not possible to change the MAC Address of a network device to my knowledge.
They are coded into the firmware of the device itself and assigned by the
manufacturer.  You can always put a second NIC in the machine and Nat thru
it so it appears to come from a different NIC because in fact it would be.
Does this help?

Subject: Changing the mac address on Windows 2000 and XP

Hi all,

Is there any way to change the mac address of a LAN card in Windows 
2000 and Windows XP?

As a corollary to the question, how would one detect if a computer 
was changing its mac address? This is assuming that the network on 
which this machine is connected has DHCP enabled.
