I came across the same problem when I tried to setup my
networking environment (a mixture of windows and linux boxes
as you). I first tried Lisa, the same result!, only shares but no files were shown.
For the sake of simplicity, just leave Lisa and use LinNeighborhood
instead!. It'´s a nice utility that get installed when you install Mandrake 9.1. You can find it in the following menu :
K Menu/Network/ Remote Access.
Provided that all your boxes share the same workgroup, you will see in a Windows´s neighborhood-like screen, all your actives boxes. You can double-click on any PC shown and see all its shares. Even more, you will be able to mount and unmount any share (you will be asked where to mount a selected share).
Should you have any doubt with this utility or with mounting or unmounting, don´t hesitate and write me back!
Hope this helps
