So I have purchased this domain, say mydomain.com, and would like to use it for my lab in the cloud.
I spinned up a new service in Azure, say myservice, and built a new VM called mydc, promoted it to domain controller and configured a new forest mydomain.com, all default settings in Server 2012 R2. I am able to RDP into the new DC VM from the internet via myservice.cloudapp.net:[Azure Endpoint] and [Public IP]:[Azure Endpoint], but not via mydc.mydomain.com:3389 (or no port at all).
Should I login to the domain provider's interface and configure something to point to my Azure VM, maybe the DNS zone file ? and any extra config required on my VM ?
[this might belong on Server Fault, but figured out it must be quite a basic question on DNS, so tried here first]
