I’ve started in early summer of 1999 to investigate the Web to find a DHCP server that would allow me to just hook my notebook onto my tiny home network (a crossed cable!) without reconfiguring it every time. I could find only very large programs that had a DHCP server as one of many parts in it. Or I could find unix sources that were not that easy to port to windows. Since, I’m a curios guy, I started do develop it myself. It turned out to be quite easy and it was running within three days, or so.
