First, you need to install and enable file and printer sharing. In windows 98, you open the control panel, choose network, the add button, add service, microsoft, and file and printer sharing. You'll need to reboot after installing this, go ahead and do so. When windows 98 loads, you will want to create some new shares. right click on a folder that you want others to have access to, and choose sharing. Set the permissions accordingly. On windows xp, this is a little different, but close enough where you can use the same directions. Also, if winxp offers to create a network disk, do so, and run that disk on each non-xp machine that is on the network. After doing so, you should have access to the appropriate shares.
