Yes, I tried the usual File Sharing approach on the Windows m/c's and the mac, but they failed to communicate at all. My PC was originally set up for music, so a lot of the function could have been disabled or changed from default. Belkin were baffled when I asked them. All they offered was to turn of the router firewall. I'm not sure what I'm supposed to do withthe registry changes. I can understand the first part - changing the vale from 0 to 1, but the last bit has me baffled. Would you explain please?
