AD DNS does not resolve one specific public domain name

We have a normal AD domain with integrated DNS that is used as DNS servers for all internal clients. Works as expected, except we now have one specific public internet domain name (one website) that will not resolve. Using other DNS servers from other domains in our internal forrest or googles public DNS servers it resolves just fine. What gives?

None that have anything to do with this domain. I could however possibly solve it by actually making a conditional forwarder for this domain name and use our ISPs DNS, bypasing our internal DNS?

There are several reasons why it won't resolve, you need to check the following (NOTE: Not all may apply to your scenario):

The forwarders that the AD DNS Servers are using aren't resolving correctly.  Try change the forwarders to google's public DNS and test
The forwarders that the AD DNS Servers are using aren't resolving correctly.  Try remove all forwarders (not conditional forwarders), so that root hints are used instead
Check that you do not have a DNS zone which matches the DNS Domain (or parent domain) that you are trying to resolve

Hi,

Check, Check, Check. Still the same.

Do you have any conditional forwarders which might influence the lookup?

Could you also tell us the DNS name that you are having issues with so that we can give more specific details on what to look for.

No one else gave a correct answer. This "bypass solution" ended up fixing my issue.
