Server 2016 r2 dns not updating
This is because the client will not update itself due to the current record in DNS is beyond the lease period.
“ DHCP Name Protection The DNSupdateproxy group must be secured if Name Protection is enabled on any IPv4 scope Credentials for DNS update should be configured if secure dynamic DNS update is enabled and the domain controller is on the same host as the DHCP serverriginally posted this in 4/2006, and updated throughout the years, but I still get questions from time to time asking why updates are not working, especially PTR.Well, I thought it’s time for an update and to just offer a summary in the beginning, because in this day and age, no one wants to read!For example, some folks believe that the DNS servers or other DCs not be running DHCP should be in it. Make sure that NO user accounts are in that group, either.(I hope that’s crystal clear – you would be surprised on the number of responses I get asking if the DHCP credentials should be in this group.) You Just to be crystal clear, this means that if the lease is an 8 day lease, than NOREFRESH should be 4 (four) and REFRESH should be 4 (four) so when you add them together, they are not greater than the lease length.
