NetBEUI (NetBIOS Extended User Interface)

 The program that lets computers communicate within a local area network. NetBEUI is the best performance choice for communication within a single LAN. Because it does not support the routing of messages to other networks, its interface must be adapted to other protocols such as TCP/IP. A recommended method is to install both NetBEUI and TCP/IP in each computer and set the server up to use NetBEUI for communication within the LAN and TCP/IP for communication beyond the LAN.
