        This document discusses the interaction between Microsoft® Exchange Server 2000 and Microsoft Active Directory® directory service. Unlike earlier versions of Exchange, Exchange 2000 does not have its own directory service; instead, it relies entirely on Active Directory for configuration and user information.

        In large companies, Active Directory designs can be complex. Understanding how Exchange 2000 interacts with Active Directory domain controllers and global catalog servers will help you design a high-performance, reliable Exchange 2000 service.

        This paper discusses three Exchange 2000 directory access components:
        • Directory Service Access (DSAccess)
        • Directory Service Proxy (DSProxy)
        • Categorizer

        These components perform separate tasks, but they depend on each other. If DSAccess has difficulty communicating with Active Directory, DSProxy and the Categorizer will have the same difficulty.

        The goal of this document is to enable Active Directory and Exchange 2000 designers to make the best possible decisions when deploying servers, and to help administrators troubleshoot any directory access problems that occur. To fully understand the concepts in this document, you should have a working knowledge of Active Directory and Exchange 2000.
