You cannot resume messages from BizTalk Server 2004 Health and Activity Tracking after Internet Information Services is stopped and then is restarted (870609)

SYMPTOMS

You use dynamic ports to send messages through the HTTP transport by using multiple instances of the same orchestrations. During the execution of the Business Process Execution Language for Web Services (BPEL4WS), Microsoft Internet Information Services (IIS) is restarted and some of these messages are sent to the suspended queue. Events that are similar to the following are generated:
