I think Louis meant that when the network card connected it would
request a new IP and this would be updated in AD to point to the
hostname. This probably would work, but your computer would still only
have one IP pointing to the hostname, and if your computer had all
three interfaces running, it might get confused if they all hold on to
their IP's. There is also the problem of Samba, which IP should it use ?

As for Samba AD and DHCP, you could try reading this:
