have a design type query.
We are deploying a two 2008 R2 Core DNS caching server on a DMZ. The DNS server will be used for recursive quires using the root hints (no ISP DNS servers available). We will then configure our Active Directory integrated DNS servers to use the DMZ servers as forwarder from within DNS console. Here are the questions.
1. Does anyone see any inherent problems with the design?
2. Is there anything I need to be aware of in using the cache service as I've never set an OS to facilitate the service before - normally used ISA\ TMG.
3. Is it a bad idea to do this a different way, what about opening up the AD Integrated DNS servers to use the root hints themselves - any concerns?
Thank you for looking.
