I have a domain controller set up on Windows Server 2016, the domain name for the AD domain is
example.com. Every computer connected to this domain is assigned a domain name, which I can see in the
Forward Lookup Zones of
DNS manager, for example:
DC01.example.com PC01.example.com PC02.example.com
I also have a few external servers set up which are not connected to the AD domain, but they use the same domain name, for example:
The issue that I am facing is that the DNS resolver on
DC01.example.com doesn't seem to be forwarding on requests to the DNS server that I have set up under the
For example if I am on
PC01, which is connected to the domain, and I try to perform an
webapp.example.com I get an error. I think this is because
DC01 looks at its
Forward Lookup Zones, sees that nothing is there for
webapp and just reports that it cannot be found.
In case it makes any difference, the DC has no Internet access and instead relies on an intermediate DNS server, this is at
10.0.0.2, I know that this resolver is working correctly because when I use
nslookup webapp.example.com 10.0.0.2 it works without issue.
What configuration is needed to make it so that the domain computers are able to get DNS responses for the external domains?
