I have a mediaplayer ACryan PlayOnHD, wich is Linux based. It has the ability to connect to a NFS share.
I'm running WIndows Server 2003 R2 and installed NFS on it. I was able to share a directory with NFS. On the mediaplayer I can browse to the server and connect to the NFS share. But then, no file is visible.
I don't know much about NFS, probably forgot something.
