I have Windows Server 2012 Datacenter installed on a pc on my home network. I want to use it as an always available file and media server that I can access not only on my home network, but over the internet as well. I have various devices I would want to be able to access it remotely such as my Android phone, iPad, and Windows 8 laptop. What are the absolute minimum roles and features I would need to setup on the server to get this to work. Any help is greatly appreciated. Thank you and have a great day.
