Main machine running WIN XP Pro. I have a few shared folders in All Users.
Only these folders can be seen on the network by other Win 7 or XP machines.
The main C: drive is shown as sharing, "for administrative purposes only", is the warning message when I attempt to deselect.
When a Ubuntu 12.04 machine is connected, everything on C: is shown.
What am I doing wrong? and how do I prevent it happening
