FIX: A warning is logged when you use the MQSeries adapter in a dynamic receive scenario in Microsoft BizTalk Server: "The remote procedure call failed and did not execute. (Exception from HRESULT: 0x800706BF)"

In Microsoft BizTalk Server 2006 or in Microsoft BizTalk Server 2006 R2, you use the MQSeries adapter to receive and process messages. You configure the receive ports so that they can dynamically receive messages. Occasionally, a warning that resembles the following is logged in the Application log:

Event Type: Warning
Event Source: BizTalk Server 2006
Event Category: BizTalk Server 2006
Event ID: 5743
Description: The adapter failed to transmit message going to send port "<Send Port Name>" with URL "<URI>". It will be retransmitted after the retry interval specified for this Send Port.
Details:"Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.BizTalk.Adapter.MQS.Agent.MQSBroker'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{<ID>}' failed due to the following error: The remote procedure call failed and did not execute. (Exception from HRESULT: 0x800706BF)."

When this problem occurs, the message instances change to the Dehydrated state. To complete the processing of these messages, the BizTalk default host instance must be restarted.

Note A dynamic receive configuration enables the application to select a source address (URI) at run time. The application can do this by setting the MQSeries.DynamicReceive context property to Yes, and then specifying the dynamic receive address. For more information, refer to the "More Information" section.

This problem occurs because the dynamic receive port in the MQSeries adapter does not handle failures correctly. When failures occur, the adapter logs a warning in the Application log. However, the adapter does not then perform the steps that are required to process the failed messages. These steps that are required are as follows:

• Resubmit the messages.
• When all transport operation retries are exhausted, move the messages to a backup transport.
• Suspend the messages.
