Connecting an existing domain to another windows server.
I am new to EC2's and am wanting to create a server that I can connect people on remotely. I have created a domain called "test.r1" I have a static IP on the EC2. Do i need to configure this on server manager. If so how do I do this. Through IPV4 properties. On the other server I have tried to add a domain controller to an existing domain but when typing the domain "test.r1" it displays "the server is not operational" I have been stuck trying to figure out why I can't connect my domain to this EC2
