说明：   Nb.pas is a Netbios unit that allows you to make Netbios calls according to IBM s netbios 3.0 specs. It is equivalent to the Delphi 3.0x Nb30.pas unit, except that it also compiles for 16 bit Delphi 1, and 32-bit Delphi 2 and 3. The sample project shows you how to get the MAC address of a network interface using Netbios calls. It should work on any networked PC running a Microsoft Windows network, regardless of the protocol used (Netbios running over TCP/IP, Netbeui or IPX). If you need this stuff, then you should know what I am talking about anyway.
