This question is either very easy or a twist makes it very difficult, so I'll call it moderate.
Until recently, when I turned on the computer, I got a small "menu" box which listed the three users on this home machine running W98. I could double click my name, my wife and daughter could do likewise with theirs, and all would be right with the world.
The other day I had cable internet installed, and now when we turn the machine on we get a dialog box instead asking for username and password.
I know this is easy because I've asked it before and forgotten the answer. Unless the fact that the cable installation involved turning off file sharing messed something up.
What should I do? I do not want to enable file sharing for so long as I have no firewall software on this cable connection.
