I'm trying to set up a network in my house where all computers (iMac, Desktop running Windows XP SP2, and Laptop running the same) can share files and print wirelessly. So far, I've got printing working, and other computers can see files on my iMac, but my iMac can't see my WinXP SP2 PC. It just can't. I've tried everything: sharing folders, messing with the firewall, etc. Any ideas?
