One Answer:
by 'server' do mean the computer or the web server software?
sounds like an internal problem in the network adapter or the driver that was fixed by taking down the link (unplug) and enabling again (plug), which initiated a reinitialisation of the adapter. HOWER: If you rebooted the computer, at least the driver and some internal state of the network adapter should have been reset as well, hence my question about what you restarted. It could have been a strange mechanical problem with the RJ45 connector. If it was not fully plugged in, it could have lost contact with some pins (due to minmal vibrations) and thus you lost the connection to the server. I have seen weird things myself caused by not fully pluged-in connectors (only 1 of 3 pings works, up/download speed totally different like 1:10, etc.) BTW: Regarding the SEQ/ACK. Are you really sure you have seen exactly that? They don't match the data you reported (GET request). The server should have ACKed the data of the GET request. Can you post the capture file?
