Unix DNS - DHCP - Windows

[Leonard]

I have 2 questions;

1.  I have a windows 2003 network with Active Directory and would like
to use free bsd (Bind 9) as the dns server. My question is how do I set
that up? Add the IP of the unix box running dns in the dns area of the
tcpip properties?

also,  if im running dhcp on the network, how does bind keep updates of
the ip changes corresponding with the host names on the network?

thanks
