The computers in my house are networked together over the internet connection. All the computers are windows vista except the backup which is running XP. For some reason my computer (which is running vista btw) can't seem to detect the backup computer when I go to "Network". I have file sharing turned on and I can detect all the other computers in the office. The other computers have no problem detecting me and the backup computer but for some reason my workstation just doesn't seem to think it exists.
Any recommendations on how I can resolve this?
