How to Perform the initial setup of your Mac Mini server
How to Use Your Mac as a Server:
Turn your Mac Mini into a server! Yes, that's right, with a little know-how and a little spunk, you can turn an inexpensive Mac Mini computer into a server to provide services over you network. You won't even need the Mac OS X Server, just the Mac OS X Client, so there is no extra software to buy, just the Mac Mini and it's operating system.
This video tutorial from FreeMacBlog and MacMiniColo will show you how to perform the initial setup of your Mac server. A few of the points will be obvious to some, but it is important that you start out simple so that when the time comes, you won't have to backtrack. Plus, missing any of these changes may cause some problems with your server later on.
