ISP Change and DNS resolution
Posted on 2014-02-21
We are changing our ISP and I am trying to remember how Active Directory integrated DNS (which is what we are using) gets or resolves its external forward and reverse DNS information? IE, where does the server look to, to pull this information? an external DNS server provided by our ISP? This was all pre-configured years ago and before my time.
We are using windows server 2003 and I went into dnsmgmt ->properties-> forwarders tab and under DNS domain to use "all other DNS domains" as apposed to configured IP addresses.
What I am worried about, is that I am not looking in the right area, and that when we change ISPs, our external DNS resolution will cease. Am I looking in the right area and does the setting use "all other DNS domains" force our DNS server to transparently look to any external DNS servers to pull down outside DNS information, or is the setting I am after somewhere else and need to be manually configured with our new ISPs DNS servers?
