Question : There are no hosts in my reverse DNS zone

Three workdays ago I had to change IP subnet for a customer.

It went ok, but I am still missing the hosts in the reverse DNS Zone.

------ REVERSE ZONE ----------------------
Name      Type      Data
192.168.18.3      Pointer (PTR)      dc.dkdom.local.
(same as parent folder)      Name Server (NS)      dc.dkdom.local.
(same as parent folder)      Start of Authority (SOA)      [2], dc.dkdom.local., hostmaster.dkdom.local.

------ FORWARD ZONE ---------------------

As you can see there are still some "old 192.168.1.x" records in the forward zone. How do I get rid of those?


Both zones are Active Directory integrated and secure only updates.

Dynamic DNS updates are enabled on the DHCP scope

Answer : There are no hosts in my reverse DNS zone

OH!!!! Well... By default for an authoritative zone, you should enable both secure and non secure updates. I would never have thought that this was not selected on your server. Strange...

If you have non secure updates deselected, then the updates to the reverse zone will be ignored as this is a non authorative zone for Integrated AD.

Glad it's working now.
