Adding NetBEUI as Sharing Protocol in WinXP.
NetBEUI stands for NetBIOS Enhanced User Interface.
It is simple protocol that is based on local computers names (no IPs addresses like TCP/IP).
Since it does not use the IP system it is not Routable to the Internet. In other words, you Hard Drives' content cannot be “shared” through the Internet connection with the ret of the World.
NetBEUI has less overhead, so it is very efficient in small networks (less then 10 computers), and it is actually faster then TCP/IP.
However on large Networks it produces the opposite effect, and might "bog" down the Network.
Networking is dominated by the Professional IT people and they do not like NetBEUI as a result you will always hear negative remarks when NetBEUI is mentioned.
Because it is a problem on large Networks, and it is Not Routable, Microsoft is phasing it out.
It is included on Windows XP CD ROM, but Microsoft is Not supporting it anymore. However there is nothing to support in NetBEUI when it used in a simple peer to peer small Network. Yeah, it will not be included with future releases of OSs, but that does not mean that we can not use it Now. Every thing that we know eventually will be phased out some time in the future.
