Despite attempts to avoid this, MA Guids invariably have been known to vary between one environment to the next, and in this case any Event Broker operation references to these guids need to be deleted and recreated. To avoid this it would be good if the service were to detect the problem and alert the admin to the need to either replace this with the correct reference or delete the operation(s). An initial comparison against MA name could be used to propose a likely match for the user to confirm - akin to the "partition matching" that happens when you are deploying an AD MA where the AD partition guids are different.
Edit (Adam): The auto-config will also have to be looked at here.
