In case you're curious, I wrote a little guide to get this running with NFS. Although it's heavy on terminal commands, if you're feeling adventurous:
However, I would only recommend using NFS if all computers in your network are running some flavor of Linux, simply because it will help preserving file metadata like permissions and whatnot. Otherwise, Samba is the way to go for better interoperability with Windows.
Were those locations already accessed from this computer previously?
