inheritance

Inheritance in the Active Directory™ schema is the ability to define new object classes from existing object classes. See Class Inheritance in the Active Directory Schema.

Active Directory also supports inheritance of security protections, which enables an administrator to specify access control settings on a directory object such that the settings can be inherited by child objects below the parent object in the directory hierarchy. See Inheritance and Delegation of Administration.

interface

In ADSI, interface refers to a COM interface. Each COM interface defines a set of related member functions that provide access to COM objects. ADSI defines and implements a set of COM interfaces and related APIs for providing access to directory service objects.

ISM

ISM is the Intersite Messaging Service. It supports pluggable transports for asynchronous, site-to-site messaging. Each transport serves two major roles: to send and receive messages, and to make topology queries (such as what are the various sites connected by this transport, and at what cost?).

Two Intersite Messaging Services are shipped in Windows 2000, remote procedure call (RPC), and simple mail transfer protocol (SMTP).
