Dhcp not updating dns server 2016
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.
You can manually retry DNS registration of the network adapter and its settings by typing 'ipconfig /registerdns' at the command prompt.
I can do a reverse lookup on the IP and that works but not name to IP.
When I joined the company, I noted that a lot of name lookups were failing or pointing at the wrong machines.
We've been having an issue for a while now where clients are not updating their DNS records, despite automatic updates in DHCP being turned on.
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. Our domain's zone is configured as an AD-Integrated zone with replication to all DNS servers in the forest.
Dynamic updates are set to Secure Only, and Aging is 2 hours no-refresh, 6 hours refresh intervals.
Under the SOA tab, the refresh interval is 15 minutes, retry is 10, and the expiration is 1 day. There are no DNS events in the log which suggest that something is set up wrong.
DHCP is set as follows: Enable DNS dynamic updates - always dynamically update DNS A and PTR records.
