In our network enviroment with vlans, switches are in charge of giving ips,subnet,gateway and dns to our clients. Each vlan has a different ip range.I can see that in AD DNS Server, clients are able to register their HOST A records fine with no issue. In reverse lookup zones(each vlan different ip range has its own reverse lookup zone) clients are not able to register their ptr records. 

After reading this link : https://supportforums.cisco.com/discussion/11361936/dhcp-auto-registration-ms-dns

I tested it with 2 clients and the clients where able to register their ptr records in reverse lookup zone. 

Question : Who notifies the DNS Server to update Host A record and PTR Record for a client because as far as i know using MS DHCP in previous clients i have never had this issue. 

Is it the DHCP Server that notifies DNS server to update the records for the clients?

Default Windows behavior for machines on DHCP: Windows updates A record, DHCP updates the PTR. Which make sense if you think about it.

You can use a GPO to fix it. This guy figured it out: http://setspn.blogspot.nl/2013/06/windows-7-reverse-lookup-dns.html

Thank you Willem for the info and the link for the gpo setting. Just to clarify things up. Our client computers are able to be authenticated in our AD Integrated DNS (secure updates only) and register their A record. Since we are not using MS DHCP server the issue could be that our dhcp server switches are not able to register computer ptr records either configuration issue or authentication issue with Kerberos correct?
