I have been running a P2P network with my four office computers simply to share a broadband internet connection. However, I am thinking about utilizing MS Exchange to make it possible to share my database and calander (in MS Outlook)with others. But, this requires me to upgrade from Win 98SE to Win 2000 on the four computers. Is this too much hassle for such a little benefit? Are there additional benefits I would enjoy from this upgrade? Are there any better alternatives? Any feedback on whether this would be worth the money and the effort would be much appreciated.
