That doesn't exactly seem to be the case from your experience, but might be close.... Massimo, are you able to pull a wireshark trace and check the DHCPREQUEST Packet?

There should be a flag set to "1" if the client is supposed to update both the A record and PTR record.

in the TCP/IP settings of the network interface: As much as it may appear strange, this is the only solution to ensure Windows will register both the A and the PTR records for a DHCP network connection; otherwise, it will only register the A record. sends option 81 and its fully qualified domain name to the DHCP server and requests the DHCP server to register a pointer resource record (PTR RR) on its behalf.

The dynamic update client registers an address resource record (A RR). the DHCP server can be configured to instruct the client to allow the server to register both records with the DNS.

If the Machine is not generating a unique SID, then an Active Directory integrated DNS will have the option to be set as allowing secure updates only.

In Windows 2008 and above, there is an option in the DHCP scope to set up the DHCP server to automatically update the authoritative DNS servers with the host (A) and PTR) records of the DHCP clients.

I can do it manually by going through the "Properties" in each client, unchecking and re-checking "Update associated pointer (PTR) record" and clicking ok in the "Forward Lookup Zones" for our domain.

Have them set to be secure and non-secure on both the forward and reverse lookup zones.

If you are working with, well almost anything network intensive these days, like Antivirus or management tools, your Reverse DNS (r DNS) lookups need to be in good shape.

But checking the boxes for "Register this connection's address in DNS" and "Use this connection's DNS suffix in DNS registration" makes it work.

I don't have a convenient test environment to try it...
