I'm afraid that you're going to have to approach this from the client end.
I've got a Windows 2012 Domain Controller running DNS and DHCP servers.
The default setting appears to be Dynamically update DNS A and PTR records only if requested by the DHCP clients.
We have multiple hosts as of late that sucessfully pull a DHCP address and are domain machines that there is no A record being created for the host.
I can do a reverse lookup on the IP and that works but not name to IP.
This reduces the need for manual administration of zone records, especially for clients that frequently move or change locations and use Dynamic Host Configuration Protocol (DHCP) to obtain an IP address.

Hello, We have started to have lookup problems in out network.
Q: Does setting DNS dynamic update credentials on DHCP achieve the same result as adding a DHCP server to the Dns Update Proxy group?
A: The short answer is no; however, it's important to step back and understand how DNS interacts with DHCP regarding dynamic updates, then look at what each of the two actions mentioned in the title actually does—namely, setting DNS dynamic update credentials on DHCP and adding a DHCP server to the Dns Update Proxy group.
