I'm new to home networking, but this is driving me crazy. I have 2 computers connected through a D-link router/switch. DHCP is enabled on both. Both computers are running XP Home, and file sharing in enabled on both computers. Each computer can see the other on the network, they can communicate well enough to play games (ie RTCW), they are sharing a printer hooked up to computer #1, and they can each use the cable modem. Now the problem. Computer #2 can access all the shared files on computer #1 without a hitch. I can read files, and move files into the shared directories on computer #1. But, computer #1 can't access the shared folders on computer #2. Every time I try I get an error message saying I don't have permission to use this resource, contact the network administrator. I have set up shared files on computer #2, I have a guest account enabled, and file and printer sharing is enabled under the network connection. It almost seems as if the computer is using access control, but this is XP home, and I can't find any access controls. Any thoughts? Thanks in advance.
