A highly portable, easily digestible road-map to configuring, maintaining and troubleshooting essential Exchange Server 2003 features. The book is organized around the 11 'MMCs' (Microsoft Management Consoles) that contain the configuration menus for the essential features. The options within each menu are explained clearly, potential problems are identified up-front, and configurations are subsequently presented in the aptly named 'By the Book' section for that MMC. Readers will also appreciate the 'Reality Check' sidebars throughout, which present valuable cost/benefit analyses of situations where there is no single 'right' answer.
