Exchange Key Concepts

Integration with Windows 2000 Server

Exchange 2000 makes use of Microsoft Windows 2000 Server technology in five key ways:

Active Directory

You can use Active Directory as a single-source directory for all of the objects in your organization, such as users and printers. With Active Directory, you can store and organize information about user accounts, such as names, passwords, and phone numbers. You can also extend the Active Directory schema to include custom attributes and object types to centralize and minimize your data administration, as well as make that data available to applications that can access Active Directory information.

In addition to storing Windows 2000 user account information, you can also store Exchange configuration and user messaging information. Because Exchange 2000 uses Active Directory, all of the directory information you create and maintain in Windows 2000, such as organization unit structure and groups, can also be used from Exchange, rather than maintaining separate directories for each.

If your messaging topology contains both Exchange 2000 and previous versions of Exchange, you can use Active Directory Connector to replicate directory information between the Exchange directory and Active Directory. This allows you to take advantage of Active Directory while still supporting your existing Exchange infrastructure.

Microsoft Management Console

Windows 2000 Server includes the Microsoft Management Console (MMC). MMC is a user interface framework that you use to administer both the operating system and other Microsoft server applications in your enterprise. MMC contains snap-ins, such as the Exchange System Manager snap-in, that control a specific set of functions within the operating system or an application.

Although previous versions of Exchange had their own separate administrator program, you administer Exchange 2000 through the MMC. Most Exchange functions are administered through the System Manager snap-in, enabling you to use a single console for managing different servers.

To find specific information about which snap-in to use for a particular function, see the online documentation for that function. For more information about how to use MMC, see the Windows 2000 MMC documentation.

Integrated Transport Protocols

Windows 2000 Server has integrated support for many of the most common industry standard transport protocols using Internet Information Services (IIS). Once you install Exchange, all of the Exchange-supported protocols, except HTTP, are administered from Exchange, rather than from IIS. Exchange supports the following protocols:

Domain Name System

Exchange requires that Domain Name System (DNS) be running in the forest where your Exchange server is installed. Exchange uses DNS in many ways, including enhancing security, resolving names for non-local message delivery, masking IP addresses, and performing reverse DNS lookups.

Windows 2000 Network Infrastructure

Because Exchange 2000 makes use of your Windows 2000 network structure, your Windows 2000 topology planning should consider placement of the global catalog and how that placement will effect Exchange sites. Ultimately, your Exchange infrastructure topology could mirror your Windows 2000 topology.
