I am attempting to network 5 macs running OS 10.3 and 2 PCs running XP Professional. I have been able to connect from the Macs to the PCs and vise versa without any problem. The problem is when I connect to a Mac from a PC I can only access the Home directory for any given user name on that Mac. I need to connect to a second hard drive installed in the Mac. What can I do?
