What is LDAP?
What is the role of the Microsoft Active Directory Connector (MSADC) ?
This event is logged if LDAP errors occur during replication between Active Directory and the Exchange Server 5.5 directory. The ADC creates duplicate objects in the Exchange Server 5.5 directory when LDAP connectivity is lost when the ADC searches for objects in the Exchange Server 5.5 directory and LDAP connectivity is restored when the ADC tries to create new contacts because of the unsuccessful search for a matching object in the Exchange Server 5.5 directory. See ME837968 for a hotfix applicable to Microsoft Exchange Server 2003.
See ME837165 for a hotfix applicable to Microsoft Exchange 2000 Server.
See MSEX2K3DB and the link to "EventID 8020 from source MSExchangeAL" for additional information on this event.
Check network connectivity. Verify the user name, password, and port address are correct, and try again. If the problem persists, verify that the remote Exchange server is configured to support LDAP. (If the accompanying LDAP message refers to LDAP_OTHER, the directory service may be out of disk space.)
