What is snap-in?

A component that can be loaded into the Microsoft Management Console (MMC) to provide a specific management capability in Microsoft Windows 2000 or in a Microsoft BackOffice server application.

Many snap-ins are available for administering computers running Windows 2000; these include third-party snap-ins for managing installable third-party applications and services. The following table shows some of the snap-ins that come with Windows 2000.

Not all of them appear in the administrative tools program group that you access from the Start menu.
