Hi all, First of all let me preface this post by saying that I am a beginner when it comes to networking and such. I am trying to learn via trial and error - and a lot of Googling and posting on various forums! It is clear to me that my knowledge is far behind that of most of the other users of this forum, as I don't understand a lot of what is talked about here! So please bear with me if I do not immediately understand your responses to my question. Let me get to me reason for posting: I have an HP ProLiant MicroServer N40L, which I use as a media server. I use it to download movies and TV shows, and stream them to XBMC on a nettop PC running Windows 8 Pro (soon to be updated to Windows 8.1 Pro), which is connected to my TV via HDMI. I also use it to download music, and access the music files via iTunes on a client PC (my Windows 8.1 laptop) in order to update my iPhone, etc. The N40L was previously running Windows Home Server 2011, which worked fine. For whatever reason, I had to reinstall Windows on the N40L. But then I thought, what's the point reinstalling a 2011 product, when I could just install Windows Server 2012 R2 on it? So I clean-installed Windows Server 2012 R2 Standard with Essentials Experience on the N40L. Prior to making the decision to do so, I had read that Windows Server is domain-only. OK, so I had no idea what that meant, but just thought I could figure it out on the fly. This is proving more difficult than anticipated. I have set up a domain on the N40L. However, I can't seem to get the other PCs on my network to join the domain. I have found a guide (this one: technet.microsoft.com/en-us/library/jj200115.aspx - sorry I can't post links yet), which seems to suggest client PCs can only have one user account attached, meaning my wife would lose all her photos, documents, etc. Am I understanding this correctly? I guess what I am after is to find out: 1) Is there a (relatively) easy way to join my client PCs to the domain without deleting any user accounts so I can watch me streamed movies on TV via my nettop? If so, please could someone give me a step-by-step guide as to how? 2) If not, I guess I will just have to reinstall WHS2011 on the N40L. But I love the modern interface of Windows Server 2012 R2 and Windows 8.1. Is there a way of getting Windows 8.1 to serve my media instead of WHS2011, and are there any disadvantages in doing so? Any input would be greatly appreciated. Thanks in advance.
