Reverse lookup zone not updating

I've also checked setting of computer which having PTR record.

It has the value in "DNS reverse zone" as your guess.

It fixed the forward DNS entries for the most part.

Please see For a static client, the client will communicate directly with the authoritative DNS server to update its PTR record.

It will first start by performing an SOA query for the reverse lookup name for the client in question: The client then receives a response from the authoritative DNS server containing information about the server that is to process the dynamic update.

As long as the Internal Domains are correctly populated, then any SOA queries for any internal-facing domains will be sent to the local DNS server.

transaction on zone Hi Moritz, Sorry for my late respond.Statically-set clients (static clients) that perform dynamic updates will send updates for both its A record (forward lookup record) and its PTR record (reverse lookup record) to the authoritative DNS server.Clients with dynamically-set network connections (DHCP clients) will communicate with both the authoritative DNS server and the DHCP server for updating A and PTR records.

  1. On DHCP server, check "Always dynamically update DNS records", and "Discard A and PTR records when lease is deleted", enable "Disable dynamic updates for DNS PTR records" is not checked;. 3. On DNS server, enable the related reverse lookup zone exits;. 4. On clients, check "Register this.
