Microsoft Internet Security and Acceleration Server 2004 SDK

IFWXPolicyChangeNotification

The IFWXPolicyChangeNotification interface includes a method for receiving a notification from the Microsoft Firewall service when changes to the configuration of the ISA Server administration COM objects are applied in a call to a Save method with the fReloadConfiguration parameter set to VARIANT_TRUE. An application filter can handle this event by reloading the saved configuration of the ISA Server administration COM objects from persistent storage to synchronize with these changes.

When To Implement

An application filter that requires the current ISA Server administration configuration should implement this interface to receive notifications that changes to the configuration of the ISA Server administration COM objects have been applied.

Methods in Vtable Order

The IFWXPolicyChangeNotification interface inherits the methods of the standard COM interface IUnknown.

In addition, IFWXPolicyChangeNotification defines the following method.

Method Description
ReloadConfiguration Receives a notification from the Microsoft Firewall service that changes to the configuration of the ISA Server administration COM objects have been applied in a call to a Save method with the fReloadConfiguration parameter set to VARIANT_TRUE and can perform user-defined operations to reload the saved configuration of the ISA Server administration COM objects from persistent storage.

Remarks

A call to a Save method with the fReloadConfiguration parameter set to VARIANT_TRUE ensures only that configuration changes that can be applied dynamically without restarting services take effect. Changes that require restarting of the Firewall service are applied during a call to a Save method only if the fResetRequiredServices parameter is set to VARIANT_TRUE. For more information, see Restarting Services after Configuration Changes.
