Hi Sorin, Could you please let us know what are the cases where these object are already existed? I just want to be sure that we free all these objects when stopping the extension. Thanks, Eitan

In this cases, when trying to add again these WFP objects the return code is STATUS_FWP_ALREADY_EXISTS, which we are interpreting as an error. This is incorrect and this patch changes that.
