Reverse lookup zone in dns is not updating

6854933580_2c8b688306_z

Update [27/06/2013]: new information regarding the topic: Windows 7 & Reverse Lookup DNS Registration [Update] In my current project we have an Active Directory domain where we use Windows DNS servers with domain integrated DNS zones.

For the reverse lookup zones we configured secure only updates.

However in the past I have seen strange behavior with the GPO settings below Administrative Templates\Network\DNS client section, and today was just the same. Below Computer Configuration DNS Client there is a setting called “Register PTR Records”.

One could think that this is pretty easy to configure, enable, throw a gpupdate in and off we go.

If your DHCP server is also a domain controller, then you are probably fine, if not, then you may want to see if the DHCP server is a member of the "Dns Update Proxy" group in AD.

Then check the Security tab on the Reverse Zone and make sure that group is authorized to create all child objects (DNS records) 2) If your statically-configured hosts are not updating the reverse zone, make sure their NICs are configured to register their IP in DNS (Windows hosts are enabled for this by default).

Microsoft is conducting an online survey to understand your opinion of the Technet Web site.

Updating the PTR records means a client registers his name and IP in the reverse lookup zone.The Active Directory Installation wizard does not automatically add a reverse lookup zone and PTR resource records, because it is possible that another server, such as the parent server, controls the reverse lookup zone.You might want to add a reverse lookup zone to your server if no other server controls the reverse lookup zone for the hosts listed in your forward lookup zone.On the DNS tab enable DNS dynamic updates and set to "Always dynamically update..." Also enable Dynamic Update for clients that do not request updates.1a) Even if these are enabled, you might need to make sure the DHCP server has permissions to update DNS records. The forward DNS entries ("A" records) for windows machines on the domain are populated automatically.
