That is NOT over the internet, but is simply through the network. We are running 4 XP Pro Dell computers with Office XP Pro installed. They are networked on a Linksys Wireless Cable DSL Router with one hard wired to the router. Our internet is DIAL UP and sharing it sucks (Okay, I am stupid and cannot get it to work so one dials up and all share it -- I had it working once but whenever you reboot the internet dialing computer, sharing went away and could not be reconnected). The poeple in the office would like to be able to communicate with each directly over the network. Can it be done ? How ? Any sites with "directions" ? Help ! Thanks !
