I'm testing some migrations from an SBS2003 domain to a Server 2012 domain.
My current setup:-
SBS2003 - schema upgraded to 2012, exchange removed, DHCP disabled, DNS replicated
Server 2012 - Domain Controller running Exchange 2010, DNS replicated, DHCP
I'm now trying to add another Server 2012 as a member server, but when I attemt to join the domain, I get an error:-
An Active Directory Domain Controller (AD DC) for the domain "TUC.LOCAL" could not be contacted.
If I click on the details button it tells me that DNS was successfully queried and that the following domain controllers were found by the query:-
However, no domain controllers could be contacted.
Yet, I can ping both by name and IP and get responses from both.
This new 2012 server is getting it's address from DHCP and the DNS is listed as the IPs of both servers
