DNS Conditional forwarders. How to forward some domains externally, some subdomains internally.
Posted on 2014-08-07
I have remote site where users are logged into a windows domain. This site is not part of our main company. Say our main company is Microsoft.
Issue is, I want this remote site's DNS, to forward some DNS requests to our DNS servers for local resolution, and some DNS request on our domain to be resolved on the remote site DNS, which will get forwarded to the root server, AKA external websites.
So, by default I want ALL microsoft.com requests to forward on to our DNS server. However, there are some exceptions to that same domain, that need to resolve on that DNS/root dns servers, for public DNS resolution.
Only catch is our local DNS servers do NOT resolve externally domains at all.
AKA lets say mail.microsoft.com, remote.microsoft.com and login.microsoft.com I want to resolve externally, so those need to stay at the remote site. But ALL other microsoft.com subdomains need to get forwarded to our main company's DNS.
How would I do this on windows server 2003/2008?
