Your friend has a small design shop with Windows NT 4.0, Windows 2000, and Windows XP workstations. He has one older Windows NT computer acting as a file server and a LINUX computer running as a firewall on the DSL line. Previous to the current network set-up, your friend’s shop used what he assumed was the default Windows networking scheme – NetBIOS over NetBEUI. Now a new client wants your friend’s shop to log on to its WINS sever so they can share resources more directly. With security in mind, what do you tell your friend to do? Why? What are his (and his client’s) alternatives?
