>I could use two books on Win XP for two different purposes. I need one for non-computer-literate people whom I assist, and another for myself. I have the basic knowledge of windows that any programmer is likely to have, but not much beyond that. I need to know more about configuration, security, networking, IIS, and so forth. But I'm not training to become an actual sysadmin.
