Security DNS

By bvergara ·
I have an external DNS with Windows 2000. How do I do to allow recursive querys of specific networks or only allow querys of specific zone (e.g. internal zone) and don't response for other not owner zones?

You should know what are recursive queries. In simpe words, that means that a "server", when he can't find any records about a DNS resolution request from a client, forward queries to other "servers" which are authoritative for him, and then, after finding the information, transfer it towards the client. To pass recursive queries, you should implement forwarders and set only specific DNS server (IPs).
The queries resolution are usually used by the clients in the domain, with the DNS IP pointing to your DNS server. I don't really understand what you mean by "not responding for others".
Hope this helps.
