How to query two different DNS server

[Guest Saqib Ali]

Is there a way to setup Windows 2003 Servers to query a different DNS

server if the record is not found on the first server?

 

This is not same as defining secondary dns servers......

 

Thanks

In general, NO (based on what you likely mean by this.)

DNS clients query ONE working DNS server -- they will try additional

server(s) IF the first does not respond but even a Negative response is

considered valid and correct if the DNS server is alive.

 

DNS Clients presume that EVERY DNS server they have configured

(on the NIC->IP properties) will return the correct AND SAME answers.

 

The trick is to make sure the DNS server(s) used by the client either have

the necessary information or that they (the DNS Servers) can contact

another DNS server which does.

 

DNS Servers typically do that off-server resoluton by one of these methods:

 

Recursion -- working downward from the top of a DNS hierarchy

Forwarding -- to another DNS server which takes over the responsibility

 

There is also:

Conditional Forwarding (as of Win2003 DNS) which is a variation on

forwarding that allows for forwarding to DIFFERENT DNS Server (sets)

based on the domain/names to be resolved.
