I saw the re-di-event-service-not-listening and I'm having similar problem.
I worked in the same PC (Windows Server 2003, SBO 2005B PL04) server and client. And the MSMQ is installed in Workgroup mode. I know already DI Event Service tries to create a public queue but it is impossible to change to Domain mode because serveral application is running with SBO server in real business environment.
Trinidad described she is planing to create private queues instead of public ones, so I want to know about it.
And when I tested another environment that server and client are serperated as two PCs, some kind of error was occured.(but it is executed successfuly in one server environment.)
