Reverse lookup zone not updating
The internal DNS backend currently needs a restart of Samba to take effect. 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.So, we already enabled Scavenging and Aging on our server, and now we want to setup a Reverse Lookup Zone.
In our case we select “Primary zone” and we want to store the information in Active Directory. Now you have to set Dynamic Update for DNS entry’s.
It's not just for resolving IP addresses into names and vice versa.
