Microsoft dns ptr records not updating

However in your aging settings, the record is able to be marked for scavenging after 8 hours (no-refresh refresh intervals). Under Server Manager, have you tried running the Best Practices Analyzer against DNS and DHCP, to see if that gleams any info?So are the records being scavenged before DHCP has an opportunity to refresh them? Run a dcdiag on your DC as an overall health check?Discard A and PTR records when lease is deleted Dynamically update for DHCP clients that do not request updates Our domain's zone is configured as an AD-Integrated zone with replication to all DNS servers in the forest.As far as my understanding goes (which is clearly not far enough), DHCP should update DNS as soon as it itself updates.At the same time, I'm combing through AD and rationalizing group memberships.The Dns Update Proxy group, despite its description, had a domain admin account and the BES Service Account as members.I did a bit of reading and discovered that the group should have DNS computer accounts in, if the zones are configured to only be updated securely - which they were. I am forever getting incorrect / outdated lookups when connecting to machines.

Discard A and PTR records when lease is deleted Dynamically update for DHCP clients that do not request updates As far as my understanding goes (which is clearly not far enough), DHCP should update DNS as soon as it itself updates.

In the Advanced TCP/IP settings of each clients network adapter, is "Register this connection's addresses in DNS" checked? I've picked two records that are out of date - the owner is SYSTEM.

Neither of these had the service account in the permissions list.

I also read that a service account should be configured to carry out the zone updates - which I have now done. The Dns Update Proxy group should contain the computer accounts of your DHCP servers, so DC1 and DC2 in your case.

In DNS console, find an outdated record, go to the Security tab and take a look at the owner of the record.

DC1 has DNS servers setup as itself and DC2 (primary and secondary)DC2 has DNS servers setup as DC1 and itself (primary and secondary) Do you have an account set up as proxy for the DHCP server to register users?
