With 2 new 2003 AD servers should I set-up the secondary server DNS
Secondary or Primary? I tseems like the second AD server should be a
secondary (backup) to the first server. However, what happens if the first
server goes down?

Read FriscoKid's response.

Never make the 'backup' DNS server another primary;
two primaries will never replicate with each other (nor
will a Primary replicate with an AD-Integrated "set" of
DC-DNS servers.)

AD-integrated is a much better choice in almost all cases
but can support ordinary primaries if you have a reason,
e.g., NT secondary, UNIX secondary, or no-DC at a
location where you need DNS (but chances are if you
need a DNS server for a domain there, you also need
a DC.)

The only time you create Primary-Primary is for "shadow"
DNS to "split" your DNS for external public view and a
different internal private view. Note you use the two
Primaries specifically to "break" replication so that internal,
private records will not flow outside automatically.
 
My first DNS server is already set-up as AD-Integrated. The only way to get
to the AD-Integrated button on the second DNS server is to make it primary
and also select the Ad-Integrated button. This would make my DNS configs
part of AD and allow me to manage the 2 as one? ...Scott
