If your DHCP server is also a domain controller, then you are probably fine, if not, then you may want to see if the DHCP server is a member of the "Dns Update Proxy" group in AD.
Then check the Security tab on the Reverse Zone and make sure that group is authorized to create all child objects (DNS records) 2) If your statically-configured hosts are not updating the reverse zone, make sure their NICs are configured to register their IP in DNS (Windows hosts are enabled for this by default).
The reverse lookup zone exists, and I can add entries to it manually, but it doesn't automatically populate.

The DHCP client will communicate with the authoritative DNS server directly for updating its A record, but the DHCP server updates the DNS server with the client’s PTR record In some cases, a DHCP server may update a client's A record on its behalf, even if the client did not specifically request this.
This can occur with non-Windows machines that may not be able to request dynamic updates.
Microsoft is conducting an online survey to understand your opinion of the Technet Web site.
If you choose to participate, the online survey will be presented to you when you leave the Technet Web site.
Since there is no dynamic reverse lookup zone, the registration fails, but the DHCP database cleanup, performed every 60 minutes, attempts the registrations that previously failed.
If the client has moved to a new IP subnet, the the A record is registered using the old IP address.
If there are missing entries, you likely have your DHCP missing one of two settings: This is required if you have DHCP installed on a Domain Controller.
