I've Windows 2016 DC on domain Super.Dom. I've setup conditional forwarder in DNS for domain test.dom. Now this test.dom is a separate domain and so it has multiple other domains setup on it. Including some external domain external.com.
For some reason queries for external.com return results from "local" subnets instead of using external forwarders (220.127.116.11/18.104.22.168).
So it would seem DNS is using conditional forwarder of test.dom to deliver answer for external.com which is weird (at least unexpected). Is that standard? How can i force Windows DNS to only use conditional forwarding for test.dom (and maybe subdomains of test.dom) and not return anything else from other domains?
