Solidifying Core Technologies for Exchange 2003

Although this chapter has covered a variety of new features, functions, and capabilities built in to Exchange 2003, there are also a number of core technologies that Microsoft improved as well. Some of these core technology improvements come in the area of DNS improvements, reliable Global Catalog lookup improvements, tools, and strategies for successfully planning and migrating from Exchange 5.5 and Exchange 2000, and core technologies at leveraging Windows 2000 and Windows 2003 capabilities.

Solidifying DNS for Proper Message Routing

Domain Name System, or DNS, has been the core name resolution technology for Active Directory from which Exchange 2000 and Exchange 2003 extend the directory lookup scheme. Having a solid DNS infrastructure is critical to the success of proper email message routing. Organizations that do not clearly understand how to implement DNS, or integrate Active Directory DNS with existing Unix-based enterprise DNS systems, can impact efficient and effective message routing.

Chapter 7, "Domain Name System Impact on Exchange Server 2003," covers the basics as well as best practices and lessons learned at implementing DNS, which improves name resolution for an organization. Chapter 7 also addresses a core infrastructure need for reliable message routing and communications.

Deploying Global Catalogs for Reliable Directory Lookup

Global Catalogs are the directories used within an Active Directory or Exchange messaging environment for looking up other internal email users and distribution lists. Microsoft made changes in Windows 2003 on how Global Catalogs can be positioned in the Active Directory. The improvements in Global Catalog caching, replication of site information, and distribution list information have changed the way many organizations operate .

Chapter 8, "Global Catalog and Domain Controller Placement," covers new tips, tricks, and techniques on GC and DC placement, and provides a method in which the number of servers can be reduced, or at least optimize systems for better directory lookup and replication.

Completing a Migration to Windows 2003

Some organizations might still be running Windows NT4 or Exchange 5.5 and will take this opportunity to make a major upgrade to Windows 2003 and Exchange 2003. There are many reasons highlighted in this introduction chapter on why to upgrade to the latest Windows and Exchange systems, but Chapter 14, "Migrating from NT4 to Windows Server 2003," and Chapter 15 focus on specific areas for planning, prototype testing, and successfully completing the migration process.

Upgrading is not just getting the latest operating system and messaging system from Microsoft; the upgrade also provides the Exchange administrator with a more reliable messaging system with tools that help keep the system more secure, run more efficiently , and provide access from virtually anywhere and from any device in use in an organization.
