The IFWXLowResourceRecoveryOperation interface is the application filter interface that you implement to respond when a low resource failure occurs. For a description of the low resource recovery mechanism, see the Remarks section of this topic.
The IFWXLowResourceRecoveryOperation interface inherits the methods of the standard COM interface IUnknown.
In addition, IFWXLowResourceRecoveryOperation defines the following method.
|Recover||Implemented so that your application filter responds appropriately to a failure caused by low resources.|
To use the low resource recovery mechanism, your filter has to register with the Microsoft Firewall service using the IFWXLowResourceRecoverer::RegisterForLowResourceRecovery method so that the filter will handle failures. When a failure occurs, the filter can check the error message to ascertain whether the failure was caused by low resource availability. If so, the filter calls the IFWXLowResourceRecoverer::SignalLowResourceFailure method, providing a cookie identifying the failure, and indicating to the Firewall service that the filter wants to recover from the failure. The Firewall service then calls the IFWXLowResourceRecoveryOperation::Recover method, which can retry the operation periodically until it succeeds.
