Remote COM+ Events - Question

I've got a FireEvents app and an EventSubscriber app, along with an EventClass. I want to run the FireEvents app on a machine and have the EventSubscriber app run on 2 other remote machines. Right now, if I export the event "app proxy" file to the "FireEvents" machine from one of the other "EventSubscriber" machines, only that machine where I exported the "app proxy" file from will see the fired events. Does anyone know how to set up the EventClass so that subscribers on multiple machines can see the fired events. Thanks ... Rick
