I have up to 5 computers on a wireless Windows network. Some are running W2k and some are running XP. I want to be able to access each of the computers from each other without having to authenticate each other between computers. How do I set up users and passwords to accomplish this? In other words, when I am using one computer, and try to access a resource on another computer, I am now challenged to logon with a username and password. I don't want to have to do that for users that are behind the router.
