Messages from the MQSeries Bridge Are Sent to a Dead Letter Queue

If send permissions are not set for the Everyone group on each destination Message Queuing (also known as MSMQ) queue, messages from the Message Queuing MQSeries Bridge end up in a dead letter queue with class "Access denied."

If you remove the Everyone group, only users or groups who are permitted to send messages can insert messages in the queue. For the bridge, this means that you must have connectivity with domain controller to enable access checking and to convert the MQSeries UserIdentifier into a Microsoft Windows user security identifier (SID). If the bridge cannot convert the MQSeries user identifier into a SID, it sends messsages to the destination Message Queuing queue as anonymous. The Everyone group must have send permissions so that anonymous messages are not sent.

This hotfix permits the administrator to configure the bridge to send a message to the destination queue as a specified user. If the bridge cannot resolve the MQSeries UserIdentifier to a SID, it sends the message to Message Queuing with a default user SID that was read from registry.
