COM lets you control IIS from scripts or programs. This means, respectively, accessing the FTP server, the virtual directories, and the computer on which IIS is running. From these interfaces, site administrators will use COM as the conduit to reach into IIS and manage its services through a set of predefined COM objects. The low-level object, also known as the Admin Base Object, provides services to administrative APIs. Some of its applications include creating a new Web server, FTP server, and virtual directories, as well as customizing the IIS installation process.
Objects encompass other objects to create the object structure.
This object hierarchy lets you access metabase properties that determine configuration settings for specific IIS elements. The IIS Administration Objects are namespace providers in support of the ADSI standard for remote administration of directory service namespaces. The IIS namespace is composed of the IIS Administration Objects and the metabase. ADSI simply provides a standard syntax for addressing IIS configuration data. For example, using ADSI, a site builder can add users, manage printers, or create virtual Web servers.
