Multiple Domains, Multiple DNS, over VPN
Posted on 2013-01-28
we have two facilities connected by an open VPN tunnel between them. Each one has its own AD, DC and its own DNS. but of course we need to share information between the two.
I have been working to get the DNS for DomainA available to DomainB and vice versa, and i have been 50% successful to this point.
for some reason, I have been able forward the DNS from DomainA to DomainB, but I cannot get the DNS on DomainB to load on the DomainA server.
When I attempt to add this zone to the DomainA server I get an error stating that "the server with this ip is not authoritative for the required zone"
which is where my confusion is....to my knowledge I have the same settings on both servers, so I am not sure why this one won't set up?
I have DomainA listed as a Name server on DomainB and setup DomainB to allow zone transfers to any servers listed as a NS.
anything glaring that I should check?
one other thing I have noticed is that when at DomainB, if I want to search for a computer on DomainA, I have to enter the FQDN and not just the DNS name in order to find it? is that normal?
