Welcome to our new Microsoft Q&A Platform.
Please refer to the following steps:
Go to DHCP client,set the following Registry value on the DHCP client to force the DHCP client to honor the DHCP Server configuration in regards to Dynamic DNS updates.
Value: 2 (DHCP Server overwrites DNS client)
Valid Values: 0 (No overwrite), 1 (DNS client overwrites DHCP server, default) or 2 (DHCP server overwrites DNS client)
A restart of the client is required for the change to take affect.
Depending on environmental circumstances, it may be necessary to delete Host A and/or Pointer ( PTR ) records whose ownership resides with the DHCP client and not the DHCP to allow the DHCP Server to successfully update Client DNS records.
Note: Make sure that you back up the registry before you modify it. Make sure that you know how to restore the registry if a problem occurs.
