Windows dns not updating

What is even more confusing is the effect you see if the zone is set to "Nonsecure and Secure". This unexpected response to SSSD will generate an error. Hopefully this explains a number of scenarios and how to set to proper configuration.

Server: win-dc03.rakhesh.local Address: Non-authoritative answer: (root) nameserver = a.(root) nameserver = b.(root) nameserver = c.(root) nameserver = d.(root) nameserver = e.(root) nameserver = f.(root) nameserver = g.(root) nameserver = h.(root) nameserver = i.(root) nameserver = j.(root) nameserver = k.(root) nameserver = l.(root) nameserver = m.a.internet address = My DNS server doesn’t have an authoritative answer (notice the output above) because it only has the info that’s present with it by default.

That looked like it was doing something but then failed with a message that it couldn’t get the root hints. The real answers could have changed by now (and it often does – the root hints list that these servers come with can have outdated entries) but that’s fine because it has some answers at least.
