How should I configure the DNS server's network interface

I have a windows server 2003 AD server that's running DNS.  The Network interface has a Static IP address.  There is also one other DNS server in the domain.

Should I allow the network interface card to obtain DNS server addressess automatically, or should I assign DNS servers to it?

If I assign, do I assign it's own address as the preferred DNS address and the other DNS server as the Alternate DNS server?  Am I supposed to assign a public DNS server here instead?

What's the best practice?

Best practice is that you assign the servers address as the Primary DNS and the second server as the secondary DNS.  If the zone is AD integrated, then both DNS servers will update from AD so long as they are both DC's.  From there you can choose to use ROOT HINTS as your forwarder or setup the external DNS servers for your ISP as DNS forwarders in the Zone configuration.  I always use the ISP DNS servers as my forwarders (shouldn't need more than 2 - 3 DNS forwarders).

As for the clients, if you have an internal DHCP server, just add your DNS servers to the 006 DNS Server Option (if using Microsoft DHCP).  Otherwise, you will need to refer to your DHCP servers documentation.
