Use the Register Native Module and Edit Native Module Registration dialog boxes to add or edit native modules that process requests made to the Web server. IIS includes many native modules to process parts of requests, such as the BasicAuthenticationModule module that performs authentication for users in applications that use Basic authentication.
After you register a native module from this dialog box, you must also add it to the Modules list on the Web server before the module can process requests; you can do this from the Add Native Module dialog box as soon as either the Add Native Module or the Edit Native Module Registration dialog box is closed.
