I've already setup my AD Server (Server 2012). Have yet to connect anything to it though. My only concerns are those devices i have on my network that stream files off the file server. For example i have those little WD Live TVs that i use to stream media files of my network. Of course the WD Live TV is not going to be able to join a domain show how would i go about accessing my files after i join the computer to the domain? I stream a variety of video formats mpeg2, mp4, avi, wmv, mkv , ect... . I also stream other files like music.
