Tried everything I could think of - disabled software firewall, routed ports, even set up DMZ and temporarily turned off router's built in firewall temporarily. No avail.
Could I ask how the server is attempting to send the information to the client - in particular the port number(s) you try to use?
Further troubleshooting - Process Monitor says connections are successfully established for javaws.exe, but Wireshark says no packets are transmitted on the opened ports. I'm suspecting software or Windows firewall.
Searching for the error online - connection resets are usually established connections, but somewhere one side or the other drops the connection early for some reason.
Tomorrow I will try to investigate further.
