IFWXPolicyChangeNotification Interface

Article
08/13/2010

The IFWXPolicyChangeNotification interface includes a method for receiving a notification from the Microsoft Firewall service when changes to the configuration of the Forefront TMG 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 Forefront TMG administration COM objects from persistent storage to synchronize with these changes.

Syntax

interface IFWXPolicyChangeNotification : IUnknown

When To Implement

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

Methods

The IFWXPolicyChangeNotification interface inherits the methods of the IUnknown interface.

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 Forefront TMG 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 Forefront TMG 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.

Requirements

Server	Requires Windows Server 2008 R2 or Windows Server 2008 x64 Edition with SP2.
Version	Requires Forefront Threat Management Gateway (TMG) 2010.
Header	Declared in Wspfwext.idl.
