Got a problem. All of a sudden I get this message whenever I try to access one of my computer's shared folders (Computer's nickname is "Green") from any of my other computers (4 others) using WinXP Pro. No problems with any of the others talking to each other. No problem with Green reaching out to other computers on the network and looking at their shared folders. Same router, same switch, nothing new that I know of, just suddenly stopped allowing other computers access and adds that comment in the dialog box. Any thoughts? Thanks.
