This section contains an alphabetic reference to the IIS metabase properties, and supplementary information about the use of the reference. The IIS metabase contains the information about how the IIS server is configured. For more information about the IIS metabase, see IIS Configuration Storage. For information about how to configure IIS, see IIS Administration Technologies and Configuring Metabase Properties.
When setting metabase properties, make sure you use the correct format. Incorrectly formatted metabase properties are either ignored by IIS or cause unexpected behavior.
This section includes the following topics:
