I use both a personal laptop and my family's pc, the former largely for actual use and the latter largely for storing files (because other people are using it). What I'd like to do is set up both computers so that (a) my laptop files are not accessible from the rest of the network; (b) my personal files on the family computer are not accessible by other users; (c) my personal files on the family computer are accessible from my laptop.
After running into an obstacle with sharing privileges that I somehow solved by accident (my user account folder had been set as both private and shared on the network, and both checkboxes had been greyed out until the computer suddenly realized there was a problem with this), I think I've accomplished goals (a) and (c) but left (b) behind. If I understand the system correctly, I could add a user account password to accomplish (b) but at the expense of (c). What can I do to fix this?
(I should probably mention that my OS/Product stats are for the family pc; my laptop runs Windows Vista w/ Service Pack 2. I have an administrator account on each.)
