We have a single windows 2012 R2 which we have configured into 2 virtual machines using Hyper-V,
We can ping each of the servers OK.
We created a local domain called companyname.co.uk
We installed DNS & DHCP services, and all looked OK, however when we try to add the second server to the domain, we get the "Welcome to the new domain" notice, which seems to confirm that all is well, but a couple of minutes later we are told :-
" changing the primary domain DNS name of this computer to "" failed. the name will remain companyname.co.uk
the error was
the specified domain either does not exist or could not be found.~
Once restarted, the server still reports that the server IS part of the domain, but we find no new entries in the DNS listings, and we cannot browse the network.
We CAN connect to the server using \\servername
When we ran DCPROMO we did receive an error ... A delegation for the DNS server cannot be created because the authoritative parent zone cannot be found...
Having looked at this, I seem to find that as this is our only DC, we can ignore the message?? Is that the case?
I am pretty lost now, so would welcome any assistance in trying to resolve this issue.
One other thing, when we initially created the DNS, there did not seem to be any entries for the actual domain controller, so had to make them manually.
Do you think this is related to DNS?
