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

I didn't get clear answers on my questions.
- The domain is at the root of the forest and has two domain controllers
running Windows 2000 and Windows 2003. I cannot make the reverse zones on
both domain controllers AD-integrated when the DHCP server runs on a member
server. Is that the right result? I'm making the reverse zone on Windows
2003 AD integrated but the W2K DC I'm having to use a secondary zone grabbed
from the Windows 2003 DC.
- At what point will reverse zone information be populated by the DHCP
server or domain computer into DNS? Will this only happen when the lease
is initially taken?
- When will hosts with reservations on the DHCP server update the reverse
zone information on DNS?

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.
As long as the machines are pointing to the DNS server that hosts the
reverse or forward zones, the zone allows updates, and if set to Secure
updates, the machines that are joined to the domain will update them. (Do
not use your ISP's DNS server anywhere other than a Forwarder). And yes,
Microsoft DHCP supports DHCP Option 081, which works hand in hand with DNS
Updates. If using a non-Microsoft DHCP that supports Option 081, you can
tell it to allow the clients to update, but if you are using a
DHCP server that doesn't support Option 081, then it may be problematic.you
