I have a small local network with friends(router->users). Each of them has a Windows XP.
I want to add each of them to some groups in my local windows groups of users (like quests, users, administrators) . So I can let some group/user to have access to some files, but the others won't have access. I turned the simple sharing off, but I don't know how to add them to act as a local user. Just like in a FTP(each user from another computer is allowed to see certain folders) but in Windows enviroment.
How to do it?
