r udeg

is settings site b the same site in dns server properties?

did make sure udp , tcp port 53 open both ways?

did make sure resource records have been updated?

did flush cache/ scavenging happened?

did check dns forwaders , recursion?

remember if dns server fails resolve name not authoritative, cause failed recursive query. recursive queries used dns servers resolve remote names delegated other dns zones , servers.

note: if disable recursion on dns server, not able use forwarders on same server.
