Primary & secondary DNS servers

I just inherited DNS configuration for our network, and I
have a question regarding configuration of our 2 DNS
servers.

Background: Both of our DCs (DC1 & DC2) have DNS
configured, and both have an Active Directory-integrated
DNS domain for the Active Directory domain. When I add a
static entry for a non-AD host on DC1, the change never
propagates to the DNS database on DC2, even if I select
the "Update server data files" command from DC1 and/or
DC2.

Question: How can I set up DC1 to be the primary DNS
server, have DC2 be the secondary DNS server and have
changes to the primary propagate to the secondary, while
maintaining the Active Directory-Enabled features?

Thanks,

-- Geoff
 
If both are AD integrated, are set to allow dynamic updates, and if AD
replication is working correctly between them, the default settings should
allow registrations made on one should replicate to the other.
What are the settings for zone transfers and what is in the NS tab.
I guess at this point I might also question if replication is working
properly and look in the event logs for any possible problems there. Also
do the databases appear to match up with the one exception of the A record
you manually add.

Thanks for the response. It turned out "Allow zone
transfers" was not enabled. Doh! However, there were some
other settings that needed review, as well. There was a
server in the Name Servers list that didn't belong, and
WINS forward lookup was not enabled.

Thanks for pointing me in the right direction.

I wouldn't recommend you use primary/secondary zones for this both DCs
should have writable zones. I recommend you fix the replication problems.
DCDIAG and netdiag will help you diagnose this.
