Microsoft Windows 2000 Active Directory uses the Internet-standard Lightweight Directory Access Protocol (LDAP) to access information. In response to various LDAP requests, a domain controller returns responses containing field LDAP error codes, which indicate the status of the protocol operation. This article describes these error codes.
