DNS Reverse Lookup Zones

Dear all,

I have a DNS Server using Windows 2012 R2, everything was ok before I deleting the records in Forward Lookup Zones and Reverse Lookup Zones, after that the records in Forward Lookup Zones has re-created automatically while in the Reverse Lookup Zone hasn't. The type of Dynamic-Update in both of Zone I set as "Nonsecure an Secure". I've tried to restart the DNS Service many times but the PTR still not automatically re-create the records.

I also selected "Always Dynamically Update DNS Records" in DHCP server.

Could you show me how?

Regards,

NTQ

4.If the above steps still doesn't work ,check the box of Use this connection's DNS suffix in DNS registration on the DHCP client.

Then see if PTR records can be automatically updated.

Hi @truongquyen ,

You can check the box of use this connection's DNS suffix in DNS registration via script, then push script via GPO to all domain computers.

The example of the script or something along these lines:

 $adapters = Get-WmiObject Win32_NetworkAdapterConfiguration -Filter "IPEnabled = 'True'"
 $adapters.SetDynamicDNSRegistration($true,$true)
