DNS and Forwarding

[Paul Bergson {MCT, MCSE}]

Scenario:
I have multiple dns servers inside my firewall that I want to forward all
dns requests to a dns server outside my firewall for external lookups.

Question:
If my forwarded dns server fails will my internal servers do the recursive
search -or- will the dns search fail?

I'm assuming/hoping they will do the recursion themselves.

By default in Windows 2000 recursion is on by default which will cause
them to use root hints should the forwarders fail.

So you need to check on two things
Do you have recurision disabled on your DNS - right click on your
server name in your dns console, click properties and check the
forwarders tab. There is a check box for recurrsion.

second, make sure you have root hints.

With those two in place you should be good to go.

I was pretty sure it did its own recursion but couldn't find it.

Thanks for the help
