Use the Defaults dialog boxes to edit the default values of properties that have default values, such as recycling settings for application pools, limits for sites, and the application pool in which applications run. The Defaults dialog boxes do not contain properties that are frequently unique, such as site bindings or the physical path of site, application, and virtual directory content.
Each of the following objects in IIS has a Default dialog box from which you can edit default values for all objects of that type:
When you change the default value of a property, all objects of that type will receive the new value when:
You create a new object of that type.
An existing object does not already have a specific value set that differs from the default value for the property.
If you must change the value for a specific site or application, use the Advanced Settings dialog box.
For information about a specific property, select the property in the Defaults dialog box and view the information that is displayed in the property description pane underneath the property grid. You can make the property description pane larger by clicking the bar between the property grid and the property description pane, and then dragging upward. You can also resize the entire Defaults dialog box to see more properties at the same time.
