Dns host a records not updating

In the correct setup, the LDNS should point the DHCP client to a domain name server (could be itself) inside the internal network.

However, in many cases when the DHCP and DNS configurations have inconsistencies, the LDNS may direct the DHCP client to a place outside the local scope, resulting in leakage of private DNS updates to the global network.

In most cases, the DNS server is configured to automatically update its records.

The following list illustrates a typical example of how a private DNS update leaks out to the global Internet. The DHCP client first sends a query to its local domain name server (LDNS) and asks for the authoritative server for the zone of its domain name (step 3).

In our domain the DHCP server is just a member server, not the DC master, but the PTR our Windows clients send are handled by the DC master (which is our sole Active Directory domain controller).

Therefore I doubt changing the DHCP server will achieve much — but you can give it a try, of course.

transaction on zone Hi Moritz, Sorry for my late respond.In our domain the DHCP server is just a member server, not the DC master, but the PTR our Windows clients send are handled by the DC master (which is our sole Active Directory domain controller).Therefore I doubt changing the DHCP server will achieve much — but you can give it a try, of course.
