Adding XP client to a Win98 P2P network

Since Win98 uses NETBEUI, and NETBEUI is unsupported in XP clients, what is the fastest and most foolproof way to reconfigure existing clients so they can communicate with a new XP client’s IP protocol? Just blowing away the old NETBEUI doesn’t do it, and running XP’s NETSETUP floppy doesn’t do it either.
