Hello,

Thanks for the response.

JMS uses 4001 from desktop(agent) to connection server which is allowed on firewall as you can see in below table as well. To open a port in FW will be a time taking task(in my env. ! ).

So I am not sure if these problems are just because of 4002(moreover 4002 is for secure JMS which usually is required for Enhanced security mode , mine is Enabled). The agent 5.3 works well for all the OS  so I guess it cannot be just the port 4002 (unless someone can explain me otherwise).

However I will surely keep this in my mind if nothing else helps !
