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.
The error codes are described in the following table.
