Do you ever have this problem in your reverse, AD-integrated DNS zones?
- You discover an old manual PTR record that conflicts with a new dynamic registration and you delete it
- It comes back
Sure, you can also have that problem even if it doesn't conflict with a new dynamic registration--it's just that you don't normally find this issue until you're looking to see why you're having issues in the first place. And I won't go into all the problems you may have from duplicate PTR registrations.
Anyway...what do you do?
Everytime you delete it, the stupid PTR just comes back.
Here's the trick I use. Let's say the problem record is PTR 10.20.30.40;
- Go into the DNS MMC and drill down to the PTR record.
- Select the offending record, 126.96.36.199.in-addr.arpa and right-click, delete it
- Select the parent zone, in this case 30; as in 30.20.10.in-addr.arpa
- Right click on the parent zone and select to create a New Domain... from the pop-up menu
- The name of the new domain is the name of the offending record, i.e. 40
- Let this change replicate
- Delete the zone, i.e. right-click on 40 and delete it
That will permanently delete the offending PTR record and keep it from appearing again.
Hope this helps someone!
