Event subscription does not receive anything on some machines - by: fancybird

Hi ... I am seeing a problem that is repeatable. I am targeting Honeywell Experion PKS (EPKS) OPC server, specifically. When I run the application from my development machine, I don't get any events. Query categories works. Event subscription call is fine. I just don't get any events.

When I run the application on the EPKS server itself, I get events and alarms.

When I run the application on one of the EPKS stations, I get events and alarms.

But if I run the application from a non-EPKS machine, I don't get any events.

I am not sure what I am doing wrong. Any help would be appreciated. Thanks in advance.
