Re: Maintaining AD-Integrated Reverse Zone With No DHCP Server on Domain Controller

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Just a quick follow up on the original post:

- I can get a single AD integrated reverse zone to update if I add the DHCP
server to the DNSUpdateProxy group.

- I was NOT able to get a second domain controller to integrate the same
reverse zone as AD integrated. Instead I had to define a secondary. The
DC with the AD integrated reverse zone runs Windows 2003 and the DC with the
secondary reverse zone runs Windows 2000.

- Apparently the reverse IP information will only migrate over from the DHCP
server to the reverse zone when each host renews its lease? That tends to
argue for a short lease period I guess.

- When will the hosts with reservations update the reverse zone information?
The DHCP administrative application does not show *any* expiration date for
hosts with reservations, implying indirectly that no renewal process will
happen with that host.

We had the DHCP server running on the domain controller, and when we did
that we saw the DNS AD-integrated reverse lookup zone automatically
maintained. Apparently the DHCP and DNS applications cooperate with each
other? As soon as we implemented a dedicated DHCP server and stopped
running DHCP on the domain controller, the AD integrated reverse lookup
zones are no longer automatically being maintained. In fact even the
domain controller IPs are not appearing in the reverse zone (I had to
manually insert them). What is the secret to getting the AD integrated
reverse zones to auto populate when the DHCP server is on a separate
computer from the domain controller?

I am really confused on other related issues. I created two AD
integrated reverse zones on two separate domain controllers for the same
domain. They don't appear to be replicating the same information to each
other. Is the reverse zone not automatically replicated by Active
Directory? What is the point of making the zone Active Directory
integrated if AD isn't going to replicate the information automatically?

I'm also confused by the option in the DNS forward lookup Properties for
each DNS object to "Automatically update reverse zone record" (or words to
that effect). This checkbox can be selected but the next time you
re-enter
the Properties dialog for the same DNS object it is no longer selected.
Why? Morever, selecting the checkbox does *not* have the suggested
effect
of populating the DNS reverse PTR record for the AD integrated reverse
zone
in which the DNS object should be appearing. How do we get the AD
integrated reverse zone information to appear?
