What happened to the NetBEUI protocol?
NetBIOS Extended User Interface (NetBEUI) is a network
protocol usually used in small local area networks (LANs) of 1 to 200 computers. NetBEUI is fast and small and works well within a LAN, but it is not routable, which means that computers that are not located on the same local network or subnet can't use it to communicate. NetBEUI has mostly been replaced by
TCP/IP.
Support for NetBEUI was discontinued in Windows XP. You can use TCP/IP or network basic input/output system (NetBIOS), both of which are installed by default in this version of Windows.
