New to Azure, so please bear with me...
I've created a new domain (registered a domain within Azure) and then activated AD Domain Services for that domain.
So far so good.
I have created a new VM which I want to join to the AD domain and use it to administrate/manage AD
All good - I have a public IP address and an auto-assigned private IP address = 10.0.2.4
I can RDP to the new VM via its public IP.
So next I have followed this guide to configure DNS settings for the AD Service
And in the portal I discover that there are 2x IP addresses available to configure for AD DNS and here's where it gets confusing:
DNS IP addresses available =
So the first 10.0.2.4 is the same as for my new VM - implying that this VM is a DNS server, which would be news to me as it is a vanilla, unconfigured VM - all I have done is successfully RDP to it.
So why is it sharing an IP address that is somehow associated with AD DNS in Azure?
I have also tried joining the VM to the domain - it fails. It is unable to communicate with/find a domain controller.
Any ideas/suggestions what I am doing wrong or what to do about this odd DNS IP addresss conflict with the VM?
Thanks in advance
