Scenario:
I have deployed an enterprise AD based on two virtual Domain Controllers in Windows Azure. I have then domain joined to Windows 2012 R2 servers to the AD domain. The two domain controllers has been placed in the same cloud service as well as availability set. The same goes for the two domain member servers.
In addition, the two domain member servers has been configured in a load balanced set for port 443 and 25.
What works:
What I see is that the Domain Controllers can communicate with each other just fine. The domain member servers can also communicate with the domain controllers.
What doesn’t work:
What doesn’t work though is communication between the domain member servers and from the domain controllers to the domain member servers.
The above is true for IP address, NetBIOS name and server FQDN.
Is this expected when the servers has been added to a load balancing set?
If yes then how is it possible to have two servers in the same load balancing set communicated with each other and with other servers in and Active Directory Domain?
Should also add that all virtual machines are on the same virtual network and that one of the domain controllers are registered as DNS server on this virtual network.
