In our dorm room we have three computers all hooked up to a router. One PC (XP Home), one G5 (10.4) and a Powerbook (10.4). The two desktops are wired into the router with ethernet. The Powerbook runs wirelessly on the network. All three computers have the same workgroup name. The two macs have no trouble seeing each other. The PC can "see" the other macs when I browse in explorer (My Network Places > Microsoft Windows Network > Workgroup) but if I try to click on either of the Macs, I get a permission error. There is a Canon PIXMA i4000 printer hooked up to the PC and all we want to do is be able to print from the Macs. If I try to add a printer using either of the Macs, the Windows PC never shows up in the workgroup. All of the windows sharing options that I know of are enabled on the macs. What else do I need to do? Help! Thanks.
