I am running into a problem where my A records are being created without the "update associated pointer record" option checked. I thought by default when you have dynamic updates allowed that the update ptr option would be checked when the A record is created. Is this not the case?
The ptr records for the client are being created but the A record option to update the ptr record is unchecked.

is the reverse dns zone created for the correct subnet?
also, see here:
Enable DNS dynamic updates to a DNS server
On a Windows Server 2003-based DHCP server, you can dynamically update the DNS records for pre-Windows Server 2003-based clients that cannot do it for themselves.
To enable a DHCP server to dynamically update the DNS records of its clients, follow these steps:
| 1. | In the DHCP management console, select the scope or the DHCP server that you want to enable DNS updates for. |
| 2. | On the Action menu, click Properties, and then click DNS. |
| 3. | Click to select the Enable DNS dynamic updates according to the settings below check box. |
| 4. | To update a client's DNS records based on the type of DHCP request that the client makes, click to select Dynamically update DNS A and PTR records only if requested by the DHCP clients. (This update will only occur only when the client makes a request.) |
| 5. | To always update a client's forward and reverse lookup records, click to select Always dynamically update DNS A and PTR records. |
| 6. | Click to select the Discard A and PTR records when lease is deleted check box to have the DHCP server delete the record for a client when its DHCP lease expires and is not renewed. |

The subnet for the reverse zone is correct. And the client that we are testing with is using windows xp service pack 2.

Yes i have it set to always update A and PTR records.
Whats weird is that the production name servers are setup exactly like the test name servers. But production A records are created with the update ptr record checked and the test A records are created without. But the settings in both cases are exactly the same.
