I have a hybrid network of 300+ macs and 45+ pcs. We use a program now called tsstalk. It basically allows the PCs to see the entire Mac appletalk network. Mac Printers, file servers, and so on are available now for each PC. If you want the Macsto be able to access the PCs, your best bet is windows NT Server and Mac volumes.
