Windows 2000 was a major change from its predecessor, Windows NT, andsales of it did not match Microsoft's expectations. Windows Server 2003, bycontrast, has at least doubled sales of Windows 2000. One of the trickiest partsof both is Active Directory. Administrators need comprehensive, practical,reliable information on AD. The first edition of Inside Active Directory was themost highly praised book on AD for Windows 2000. This new edition is evenbetter, and will be the bible on AD for all Windows system administrators. It iswritten on the final release software, includes all the updates for the newversion, and has been tested extensively on actual working systems. It is moretimely than the previous edition, and will hit the market just as migration toWindows Server 2003 starts to climb. Furthermore, the book is now in theMicrosoft Windows Server System Series, which means that it will be fullysupported by Microsoft.
