Problems with sending Event Notifications to remote service

Hi!

Just set up my first Service Broker test. Wanted to send an Event Notification from one instance to another. Finally, the message arrives but profiler shows that the message is still being continously resent (and rejected as being duplicate). What am I doing wrong?

With best regards,

Artus
