If you want to hide a share than rename the folder that is being shared and add a '$' sign.
i.e.
if you are sharing a folder called 'Private' than remove the share from the 323, than rename the folder to 'Private$', and than re-share it.
The share is now hidden from browsing but you can map a drive to it or access it by '\\dnd323\private$'
hope this helps
