Sharing files on a wireless network

I just converted the last wired in PC (running XP Pro as do all the boxes on my home network) to wireless. Now I find I cannot open shared files on that box on any of the others in my network. Prior to this I could share files from this PC on either of my other PC’s. The problem only arose when I made this box wireless. I can connect to the Internet, and my Network Magic map shows all machines are on the network.

Can anyone suggest a solution?

Hello Jacklass1,

Could you post a screenshot of your global rules and Application rules(Focused on System) if possible.

Thanks
