The MAC address? The MAC address is a fixed, unique number embedded in the
NIC. So how do you change the MAC on your NIC card? I'm interested.

Under Linux I would issue:
"ifconfig eth0 hw ether 01:23:45:67:89:AB"
under Windows there are several Tools available. The MAC is still
unchanged in the Card itself, but no application can read that adress
directly - the driver reads it from the card and reports it to the
program. And as i said: Its absolutely no Problem to tell the driver to
report a different MAC Adress than the real one. The only way to get the
MAC Adress directly from the card is by direct Hardware Access (Which is
impossible under Windows NT) or by writing a Driver (which is not what
the author wants i believe)
