Dhcp not updating dns server 2016
And if I do a manual ipconfig/registerdns it works, every time. Pictures attached of DHCP and DNS Dynamic updates setup - this should be correct, I've always done it like this.
A DHCP lease should renew itself halfway through the lease.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.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.
Our DHCP was set to lease addresses for 1 day, for reasons which were never explained to me.I set this back to 7 days, in an attempt to give DNS a chance to 'catch up' before the addresses potentially changed again, but we're still getting incorrect DNS entries. Our settings are now an amalgam of what went before (which didn't work) and what I've gleaned from MS documentation.
