FIX: A message is processed even if the delivery notification acknowledgement fails to route in Microsoft BizTalk Server 2006

In Microsoft BizTalk Server 2006, you use the delivery notification feature in a BizTalk orchestration. A delivery notification acknowledgement would be sent to the orchestration instance after the message has been sent successfully by BizTalk Server 2006. However, in some cases, the orchestration instance stops unexpectedly before the acknowledgement is sent back. When this issue occurs, the message is sent successfully, but no errors are logged even if there is no subscriber for the delivery notification acknowledgement.
