NFS Shares + WHSv1 + XBMC

Hey

I need your help:
I have installed NFS under Windows Home Server V1 (HPx510) following this instructions:
http://www.mediasmartserver.net/2009/12/...fs-in-whs/

What do I have to do in order to share a folder under WHS so you can stream from this folder on XBMC ?
The folder that I have shared is being shown on XBMC but you have no access to the contents - All files inside this folder are not being showed.
Maybe I overlooked something. But what?.....

I'm pretty sure that the problem lies on the WHS, but I can't figure out where.

Best regards
