Setting a configuration to Do Not Change persists the previous configuration without making a change to the configuration. Enabling this setting does not alter the current setting. If you have never configured a setting, the default state persists.
An administrator may want to set a configuration to Do Not Change if the configuration is set to its default state or if the configuration is user-configurable and the administrator does not want to revert back to a default configuration upon a dock or undock event.
