Well it seems nobody has any idea

I have been able to share a public folder to the XBMCbuntu HTPC from two Windoze laptops (Samba),
a Mint 13 Eden desktop and an Ubuntu desktop via SMB (cifs I think), yet I am still unable to share a public folder from my Fedora 17 machine.
I have been trying to share via NFS, should I be using SMB instead?
Any help would be appreciated.
Cheers The Bandit.
