Once your server has been installed you are left with a .local server that provides basic file sharing. If you want to use most of the other services you will need to change you host name and decide what type of server you want to create and set up some basic DNS to make that happen. Inside the Server App is a wizard that walks you through the process of choosing a host name that will allow your server to do what you want it to. It also presents you with the option of setting up DNS for you or leaving that up to you to do manually. For most home users, having server set it up for you is probably the easiest way to get your server up and rolling. I will cover more advanced DNS in a future screencast and you can always change your DNS set up later. In this screencast I also cover some of the basic server settings found in the server tab. These settings help you set up how you want to access your server remotely and I cover each of hose settings and what they do.
