This guide describes how system administrators, small business managers, and home users can make the most of their Windows operating systems. The text is based in part upon the author's Windows 2000/XP/.NET FAQ Web site but is broader in scope and contains more in-depth information and concrete examples. A sampling of topics includes enabling network lockout for the Administrator account, configuring a server as a Global Catalog, and setting the number of authentication retries for dial-up connections.
