Question : DNS forwarders

DNS forwarders

I have DNS server in Domain1
I have DNS server in Domain2
2 domains are separate with no trust, just network connectivity.

Users workstations are connected to domain1, whenthe try to resolve names for computers that are domain2, they cannot.
Although in DNS of the domain1 I put under forwarders tab the IP address of the DNS located in Domain2.

any idea why this is happening?

thanks

Answer : DNS forwarders

Hi there,

If you simply added the IP of the other DNS server as a forwarder, then that means that ALL queries your DNS server cannot answer will be forwarded to the DNS server in Domain2. So it would actually work, but it also means that any queries for internet resources are also being passed to the DNS server in Domain2, and then in turn being passed on to internet DNS servers.

A typical setup you would use is:

1. Configure the forwarder for 'All other DNS domains' to be your ISP's DNS server.

2. Configure a forwarder for Domain2.local and point it to the IP of the DNS server in Domain2.

(and obviously do the opposite on the server in Domain2)

This would be the most efficient setup.
