Kahn was a game server browser for MS-DOS, Windows 95 and Windows 98 enabling multiplayer of IPX compatible games over a TCP/IP network. It had a very large community of Descent players originally. When Windows XP was released, Kahn was incompatible, and the creator of Kahn would "never release the source code." This incompatibility led to a slow dwindling of the community until the final demise of the Kahn IRC channel in late 2003.
