I don’t know what the capture environment was but it doesn’t seem like you are looking at the network from the OS perspective, I.e. everything that …20 is receiving. Correct me if I got this wrong.
Like you, I see the last successful exchange and the next one doesn’t get off the ground, i.e. OS doesn’t respond to the connect request. That doesn’t provide much info about what’s going on with OS. If you suspect that the OS hang is due to something on the network that OS is choking on, you would need to see everything OS sees and then correlate suspect activities to a time window where the OS stops responding.
Do you have a managed switch that can mirror ports? If so, you could mirror the port that OS is on to a port that a PC running Wireshark can look at.
