About IIS Classes

The Class object is the unit of storage in the IIS metabase. Classes define Class objects. The type of the Class defines the type of the new object. For example, to create a new property the class type must be of type Property.

The Class object lists the following information:

• The name of the class.
• The object identifier for the class.
• The globally unique identifier (GUID) for the class.
• The properties (configuration parameters) that an instance of the class must have.
• The additional attributes that an instance of the class can (optionally) have.
• Which existing classes can create instances of this class.

Note   Programs and scripts that extend the IIS ADSI Schema should apply updates in the following order:

1. Add new classes.
2. Add new properties.
3. Add properties to classes.
