Well-Known-Objects attribute

  • Article

This attribute contains a list of well-known object containers by GUID and distinguished name. The well-known objects are system containers. This information is used to retrieve an object after it has been moved by using just the GUID and the domain name. Whenever the object is moved, the system automatically updates the Distinguished Name portion of the Well-Known-Objects values that referred to the object. The file Ntdsapi.h contains the following definitions, which can be used to retrieve an object (the GUIDs that are associated to these objects are contained in Ntdsapi.h):

  • GUID_USERS_CONTAINER_W
  • GUID_COMPUTRS_CONTAINER_W
  • GUID_SYSTEMS_CONTAINER_W
  • GUID_DOMAIN_CONTROLLERS_CONTAINER_W
  • GUID_INFRASTRUCTURE_CONTAINER_W
  • GUID_DELETED_OBJECTS_CONTAINER_W
  • GUID_LOSTANDFOUND_CONTAINER_W
  • GUID_FOREIGNSECURITYPRINCIPALS_CONTAINER_W
  • GUID_PROGRAM_DATA_CONTAINER_W
  • GUID_MICROSOFT_PROGRAM_DATA_CONTAINER_W
  • GUID_NTDS_QUOTAS_CONTAINER_W
