Active Directory Connector

In Exchange 2000, Windows 2000 Active Directory replaces the Exchange 5.5 directory service. All directory information regarding Exchange recipient and configuration objects resides in Active Directory instead of in separate directories for Exchange and Windows objects. When your messaging system includes connections to previous versions of Exchange, you must ensure that your existing Exchange 5.5 directory service is synchronized with Active Directory by using Active Directory Connector (ADC). Proper synchronization between Exchange 2000 and Active Directory ensures that your Exchange messaging system functions reliably.

You may experience specific problems when managing connections to previous versions of Exchange; for example, you may need to resolve directory synchronization problems by monitoring the events that occur when replicating objects between directories.

To identify and resolve specific problems that can occur with Active Directory, see Common Issues.
