You can use the AppDisable method of the IIsWebVirtualDir object to disable a Web application that is running out-of-process. All of the application's resources are released and the application's process is terminated. Attempts to access this application will fail. You can use the AppEnable method to re-enable a disabled application. You use the AppDisable and AppEnable methods primarily when moving, copying, or renaming metabase keys. This method has no effect if the application is running in-process.
