I have this weird problem with ports refusing to connect after about 30 minutes or so. Also the ports that are currently open and active, they are fine and are able to communicate over the network, but once I close the application using that port, I am unable to re-establish a connection. I have tried switching out NICs, but it didn't solve the problem. rebooting the server would solve the problem momentarily, but after about 30 mins or so it would happen again. Another weird thing is that incoming traffic seems to be running fine. Is there a fix for this besides rebuilding the server?
