The DHCP protocol does not automatically update DNS in the event that the DHCP server changes the IP address of a client.
To facilitate this interaction, servers running Windows Server® 2008 and DHCP and clients running DHCP can register with DNS, allowing cooperation between the two.
Also, like a forward lookup zone, a reverse lookup zone can be integrated with Active Directory Domain Services (AD DS), and it can be mirrored by secondary and stub zones.
Reverse lookup zones and PTR resource records are not necessary for Active Directory to work, but you need them if you want clients to be able to resolve FQDNs from IP addresses.
Also, PTR resource records are commonly used by some applications to verify the identities of clients.
When a qualified DNS client (such as a computer running Windows XP Professional or Windows Vista®) issues an update, DHCP servers running Windows Server 2008 process the update to determine in which of three ways the server will initiate updates on behalf of the client: The ability to register both A and PTR resource records enables a DHCP server to act as a proxy for clients running other operating systems, such as Microsoft Windows Millennium Edition, or Windows 98, for the purpose of DNS dynamic update registration.
Windows 2000 DHCP clients and earlier versions of Windows DHCP client interact with DNS in different ways.
so i manually tried to add it using "ipconfig /registerdns". I was also reading something on scavenging, but that will only fix the old entries that will deleting but I'm not sure about actually getting the correct entries to begin with.
DNS servers provide domain name resolution for network resources.
Hi Everyone, I have 3 DNS servers (win2k3) integrated into AD that their reverse DNS is not updating. Both Forward and reverse DNS was screwed up to begin with.
To fix the forward, i modified the DHCP server to always update DNS when ever it adds a new client.
Then I deleted all entries and restarted all the machines (of course I set the lease time to 1 day, one day prior to do the deletion).
