How to upgrade your current messaging and collaboration system to take full advantage of Microsoft Exchange 2000 Almost half of Fortune 1000 companies have either standardized their messaging platform on the Microsoft Exchange Server or plan to migrate to it. Microsoft Exchange 2000 is a significant improvement over previous versions. In this book, networking expert Stan Reimer presents a case study of a model company that provides IT professionals with a realistic view of the migration path from Exchange 4.0/5.x to 2000, including how to contend with problems such as legacy systems, planning, product integration, implementation, system maintenance, and more. Because the migration path involves migration to both Windows 2000 Active Directory and Exchange 2000, it is unusually complex. As a result, this book is as relevant to the large corporation with multiple domains, locations, and Exchange servers, as it is to the small company with a single-server location. Responding to the ongoing demands from IT professionals for current and reliable information on the latest programming technologies, Wiley Computer Publishing introduces the Gearhead Press titles. These books, written by accomplished trainers in their respective fields, focus on using real-world case studies to give readers the best information on leading technologies. The Gearhead Press titles will be characterized by two different imprints: In the Trenchesand Point to Point. The In the Trenches titles are fast-paced books written by fellow IT professionals who have been there and done that and will introduce readers to the new technology and guide them to a high level of proficiency. The Point to Point titles invite readers to join an IT team at a model company and implement the technology in a real-world environment-complete with positives and negatives.
