Sometimes when I try to work on a system, I find that it supports more than one user. Do you know an easy way to determine which user is logged on to the computer and which domain controls the computer?

Time to forget Windows NT 4.0's GUI and go to the command line. I know of some wonderful—and easy—commands that can solve your problem. I prefer Net Config Workstation, which will tell you about the workstation's configuration. (For example, Figure 1 shows information about the notebook on which I'm writing this article.) Various command-line utilities are available to help you find information or set up a network. To learn more about some of these utilities, see Paul Niser, "Take Command of Your Management Tasks," February 2001.
