I have this LAN network, there are many PCs connected tho a router, and I want to share files between 2 of them, because of software restrictions one of them has windows XP and the other has windows 7, and I want to know if there is some software or some other way to share files between them besides the default windows shared folder stuff (because for whatever reason it keeps getting messed up and have to reconfigure it again every now and then).
