DNS Issues in a domain - PTR Records and A records Deleting when a user logs onto their workstation
Posted on 2014-04-08
I am seeing a weird issue with our domain.
We have four active directory controllers, which all provide DHCP.
The DHCP ranges for one office is 10.10.15.X and 10.10.13.X
When a computer comes online it registers it IP information in DNS in the forward zone (A record) and also the reverse zone (PTR Record).
I have been noticed that the A and PTR records will delete after a user logs into the workstation. ( I am able to replicate the issue).
I would like it not to delete the records when a user logs on.
The items that I have checked off on the DHCP servers are the following:
Under DHCP in the IPV4 Properties I have the following checked off:
Enable DNS Dymanic Updates according to the settings below:
- Always Dynamically Update DNS A and PTR Records
Then I also have the DNS Dynamic Updates credentials filled out as well.
On the scope options I have the following options enabled:
003 Router, 006 DNS Servers and 015 DNS Domain name.
Under our default polices under Computer Configuration -> Network -> DNS Client the following items enabled:
Register PTR Records and Dynamic update
I notice when I remove the credentials that the issue goes away however it does not register the PTR records.
Any information to help troubleshoot this issue is greatly appreciated, thank you!
