However, there are still some people who have these newer OS's that require the above mentioned protocols. I am focusing on two in particular in this thread - both of them install at the same time: NWLink NetBIOS NWLink IPX/SPX/NetBIOS Compatible Transport Protocol I have heard it mentioned that with the advent of the Vista OS MS did away with this protocol package, and that this continued in the Windows 7 OS.
In Windows XP under the properties for a network adapter you had the option to install extra types of protocols.
