A flag of "0" means the client updates the A record and requests that the server update the PTR record on its behalf. Also in the DHCP scope make sure == Click the DNS tab, click Properties, and then click to select the Dynamically update DNS A and PTR records only if requested by the DHCP clients check box == is set.This would mean when the default flag of "0" comes in the server will then try to register the PTR record with the DNS server(s) it is configured to update.You, as a DHCP administrator, might want to enable DNS integration in order to automatically update the DNS records dynamically with the DHCP client computers’ information whenever the DHCP server assigns the IP address and other settings to them.
Here is how you can enable the DNS integration with the Windows Server 2012 DHCP server: Once done, click OK to save the changes that you have made.
And make sure the DNS dynamic update credentials are correct and appropriate permissions are applied for this to work As I said in the question, configuring the DHCP server is not an option. It won't register DNS records for its clients, period.
They should be able to handle it, since all of them are domain members.

Also fixed missing screenshots8/3/2012 – Additional info about DHCP Name Protection and that it requires Credentials, Dns Update Proxy, but more so to secure the Dns Update Proxy group .
When a client shuts down, and later returns past the lease time, it may get a different IP address.
