So when you setup windows server you get the .local domain, how on earth do I add a custom domain? I would guess Id have to go into my domain provider and edit the DNS settings in someway but I have no idea how to get this on the server! If anyone can even find me a step by step article (I looked) it would be a great help.. The idea is to install exchange and create an on prem solution. I have the server with AD already and user accounts.
