But first some history. Those of you with some experience in managing networks back in the days of IPX and Novell Netware remember a little thing called the "login script." It was useful to map drives in DOS, set various host parameters, and force a user to patch his system when something new came out such as an antivirus update. At the time, users almost always logged in to the network because file and print services were nearly all you could do with the network. Specialized applications were still run through terminal emulation to mainframes or minis, and nobody could figure out a good reason to connect to the Internet yet. So if you didnt log in, you didnt use the network, plain and simple.
