So here's my environment:
I am running Hyper-V on my Windows 10 Host, and I have 2 Windows Server 2012 R2 Servers running on it.
Corp-DC1 Local-DC1 Corp-DC1 is the PDC of the x.Corp domain and Forest. I am attempting to join Local-DC1 as the PDC of the x.Local domain to the existing Forest, however, I am at my final breathe.
I have DNS setup like so:
On Corp-DC1, I have a zone named x.local and inside this zone, I have my Local-DC1 A record created (IP address 192.168.3.1). I also have the reverse lookup zone created and configured properly. The SOA and NS are both 'Local-DC1.x.Local'
On Local-DC1, I have the exact same thing configured for x.corp. I also manually configured the DNS Prefix to be x.local, so that the zone lookups would work.
My routing is configured correctly, as I can ping each servers IP address without a problem, however, I cannot resolve by hostname, therefore, I cannot manage Local-DC1 from Corp-DC1 in order to install ADDS.
The actual error messages I get when attempting to add the server to Server Manager on Corp-DC1 are: "Refresh Failed with the Following error: The RPC Server is unavailable." and "Configuration refresh failed with the following error: The metadata failed to be retrieved from the server, due to the following error: The WinRM client cannot process the request because the server name cannot be resolved.
I think that about covers where I'm at. I cannot figure out why the servers can't find the Host records...
