Read an Excerpt
When my coauthors and I set out to produce the second edition of the very successful Exchange Server 2003 Unleashed book, we wanted to make sure we not only added content to chapters where things have been added since the original product release, but we also wanted to make sure we went through the entire book start to finish to rewrite sections where tips, tricks, and best practices may have changed since we wrote the first edition of the book. So before we even read the old chapter content to determine what we will fix or edit, we started off by outlining each and every chapter from scratch. We thought about what we would want to make sure was covered in each chapter if we were to write the chapters from a blank sheet. What resulted was our ability to then read the chapter, add content, delete content, and make changes that met the current best practices in the industry.
Do note, this second edition of the book takes into account Exchange Server 2003 Service Pack 2 as well as earlier releases of Exchange Server 2003 (Service Pack 1, and the original Exchange Server 2003 release). This takes in account all versions of Exchange Server 2003 before the next major version of Exchange.
By taking a clean view on the appropriate content for this book, we believe we are providing to you, our reader, a fresh perspective on planning, designing, implementing, and migrating to an Exchange Server 2003 environment. The four of us (Rand, Mike, Kenton, and Joe) started working with Exchange Server 2003 more than 18 months prior to the original product release to the public. We had several clients who were large beta implementers of Exchange Server 2003 thathad dozens of servers in production using the Exchange Server 2003 beta. Now, a few years after the original product launch, we have produced this second edition of the book based on our work with organizations having hundreds of thousands of mail users. The text of this book leverages knowledge and best practices on how to successfully migrate to Exchange Server 2003.
This book is organized into 11 parts, each part focusing on core Exchange Server 2003 areas, with several chapters making up each part:
Part I: Microsoft Exchange Server 2003 OverviewThis part provides an introduction to Exchange Server 2003, not only from the perspective of a general technology overview, but also to note what is truly new in Exchange Server 2003 that made it compelling enough for organizations to implement the technology in beta in a production environment. We also cover basic planning, prototype testing, and migration techniques, and provide a full chapter on the installation of Exchange Server 2003.
Part II: Exchange Server 2003This part covers the design of an Exchange Server 2003 messaging environment for small, medium, and large organizations. It also covers the integration of Exchange Server 2003 in a non-Windows environment. We understand that the implementation of Exchange is different for organizations of different sizes. Small organizations typically do not have the need for extensive routing groups and administrative groups, so the design illustrations focus on limited server environments. Exchange for large organizations frequently involves extensive front-end, back-end, and distributed user environments, so specific design recommendations are made for these types of organizations.
Part III: Networking Services Impact on ExchangeThis part covers DNS, Global Catalog and domain controller placement, Microsoft routing and remote access configuration, and Outlook Web Access configuration from the perspective of planning, integrating, migrating, and coexistence. Notes, tips, and best practices provide valuable information on features that are new in Exchange Server 2003. You explore what's new and different that you can leverage after a migration to Exchange Server 2003.
Part IV: Securing an Exchange Server 2003 EnvironmentSecurity is on everyone's mind these days, and Microsoft knew it and included several major security enhancements to Exchange Server 2003. We dedicate three chapters of the book to security, breaking the information into client-level security, such as remote client access, message encryption, and attachment encryption; server-level security, such as encrypted front-end and back-end server configuration, certificates, and privacy and antispam protection; and transport-level security, such as IPSec, RPC over HTTPS, and system-to-system encrypted communications.
Part V: Migrating to Exchange Server 2003This part is dedicated to migrations. We provide a chapter specifically on migrating from Windows NT4 to Windows Server 2003 as it applies to planning and preparing Active Directory with Exchange Server 2003 in mind. Other chapters in this part of the book address migrating Exchange 5.5 to Exchange Server 2003, Exchange 2000 to Exchange Server 2003, and compatibility testing of Exchange add-ins and components in a Windows 2003 and Exchange Server 2003 environment. These chapters are loaded with tips, tricks, and cautions on migration steps and best practices.
Part VI: Exchange Server 2003 Administration and ManagementIn this part, four chapters focus on the administration of an Exchange Server 2003 environment. This is where the importance of a newly written book (as opposed to a modified Exchange 2000 book) is of value to you, the reader. The administration and management of mailboxes, distribution lists, and sites have been greatly enhanced in Exchange Server 2003. Although you can continue to perform tasks the way you did in Exchange 2000, because of significant changes in replication, background transaction processing, secured communications, integrated mobile communications, and changes in Windows 2003 Active Directory, there are better ways to work with Exchange Server 2003. These chapters drill down into specialty areas helpful to administrators of varying levels of responsibility.
Part VII: New Mobility Functionality in Exchange Server 2003Mobility is a key improvement in Exchange Server 2003, so this part focuses on enhancements made in the mobile phone and PDA replication tools to Exchange. Instead of just providing a remote node connection, Exchange Server 2003 provides true end-to-end secured anytime/anywhere access functionality. The wireless mobility functions provide access to Exchange, using mobile phone, wireless device, and PDA support. The chapters in this part highlight best practices on implementing and leveraging these technologies.
Part VIII: Client Access to Exchange Server 2003This part of the book focuses on the enhancements to the Outlook Web Access client, various Outlook client capabilities, and Outlook for non-Windows systems. Outlook Web Access is no longer just a simple browser client, but one that can effectively be a full primary user client to Exchange. Different versions of the full Outlook client have varying levels of support in Exchange Server 2003 relative to security,
Part IX: Client Administration and ManagementAs many organizations choose to upgrade the client software on their desktop and mobile users, new capabilities in Windows Group Policies and various deployment techniques simplify the process. The two chapters in this part of the book cover best practices, tips, and techniques to automate the client administration and management process.
Part X: Fault Tolerance and Optimization TechnologiesThis part of the book addresses fault tolerance, data recovery, and system optimization in Exchange Server 2003. Exchange Server 2003 must be reliable, and Microsoft included several new enhancements in fault-tolerant technologies and data recovery to Exchange 2003. The four chapters in this part address system-level fault tolerance in leveraging clustering and network load balancing technologies, best practices in backup and restore procedures, tested procedures at recovering from a disaster, and capacity analysis and performance optimization of an Exchange 2003 environment. When these new technologies are implemented in an Exchange messaging environment, an organization can truly achieve better enterprise-level reliability and recoverability.
Part XI: Cross-Platform Migrations to Exchange 2003The last part of the book addresses the migration to Exchange Server 2003 from non-Microsoft messaging environments. This section has chapters on migrating from Novell GroupWise and Lotus Notes to Microsoft Exchange Server 2003. The chapters cover tips, tricks, and best practices using the Microsoft migration tools for migrating mailbox content to Exchange such as email messages and calendar appointments. The section also covers the connectors that interlink Novell GroupWise and Lotus Notes to Exchange for environments where the coexistence of other messaging environments to Exchange is necessary.
The real-world experience we have had in working with Exchange Server 2003 and our commitment to writing this book from scratch enables us to relay to you information that we hope will be valuable in your successful planning, implementation, and migration to an Exchange Server 2003 environment.
