Dhcp not updating dns server 2016

We're running 2003 At the same time, I'm combing through AD and rationalizing group memberships.
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.
It does appear to be the same clients again and again with the problem, but then they could just be the people trying to get on things only available on the staff web filter policy.
The error logged when affected clients try to register is: Log Name: System Source: Microsoft-Windows-DNS-Client Date: 29/10/2015 Event ID: 8015 Task Category: (1028) Level: Warning Keywords: User: NETWORK SERVICE Computer: PCNAME.domain.local Description: The system failed to register host (A or AAAA) resource records (RRs) for network adapter with settings: Adapter Name : Host Name : PCNAME Primary Domain Suffix : domain.local DNS server list : 192.168.10.2 Sent update to server : IP Address(es) : 192.168.21.2 The reason the system could not register these RRs was because the update request it sent to the DNS server timed out.
This might be an issue, maybe someone with more knowledge can elaborate.
A DHCP lease should renew itself halfway through the lease.
So in your case, DHCP update would renew it's lease every 3.5 days, triggering a DNS refresh.

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.
The most likely cause of this is that the DNS server authoritative for the name it was attempting to register or update is not running at this time.
