Alternate DNS server problems

I have two domain controllers running DNS. DHCP assigns a
primary and secondary DNS for each user. DNS is working
ok on both machines. However if the primary server is
shut down no one can resolve DNS through the alternate
server. How can I set this up so users resolve DNS
through the alternate server. If I go to a system and
change the primary DNS setting to the alternate server it
works.
HELP!!!

Actually it assigns a "preferred" and "alternate" as those
other terms only have meaning ON THE DNS servers
(primary or secondary)

Is the secondary replicating from the primary?

What happens if you query them directly from a client using
NSLookup (or similar command) such as:

nslookup server1.yourdomain.com ip.primary.addr.ess
nslookup server1.yourdomain.com ip.secondary.addr.ess

Does these both work for a variety of records?

Does IPConfig on the clients SHOW that they have both
DNS servers set?

If so it should fail over automatically (with perhaps a burp
or two when #1 goes down for a few seconds.)

The secondary is replicationg from the primary. Nslookup

works the same on both. IPconfig show both servers>.
