Mission-Critical Microsoft Exchange 2000 is the definitive book on how to design and maintain extremely reliable and adaptive Exchange Server messaging systems that rarely crash and that preserve valuable data and services in spite of technical disruptions. E-mail systems are now a primary means of communication for organizations, which can afford e-mail down-time no more than they can afford to be without phones. Further, messaging systems increasingly are supporting vital applications in addition to e-mail, such as workflow and knowledge management, making the data they store both voluminous and incredibly valuable. Mission-Critical Microsoft Exchange 2000 teaches system designers, administrators and developers the strategies, tools, and best practices they'll need to plan and implement highly-available systems on Exchange 2000 and on earlier versions of Exchange. The book explains Exchange back-up and disaster recovery techniques, Windows clustering technologies for Exchange systems, and security planning to resist messaging-based attacks. Written by Jerry Cochran, an authority on large-scale Exchange systems, Mission-Critical Microsoft Exchange 2000 helps readers create Exchange systems upon which they can build large and growing organizations.
