I have had my Mac and my Windows 7 PC networked for some time. I just upgraded from OSx 10.5.3 to snow leopard. My Mac still shows up as networked on my PC, but unlike before all of my drives are not "mapped" to the PC. I can only access "Hard Drive 1" my system disc, and not the other two internal drives, which I could access from the PC before I installed snow leopard.

any ideas?
