Any currently open TCP connections are forcibly terminated. This is not a graceful FIN/ACK handshake closure; this is a hard RST (Reset) packet sent to the remote end (if connectivity allows) or simply a local handle destruction. This clears hanging sockets that might be stuck in TIME_WAIT or FIN_WAIT states, preventing new connections from forming.
The good news is that 80% of client-side TCP reset issues are cured by the simple netsh int ip reset command on Windows, or its equivalent on other OSes. If that fails, look to your router (reboot it) or your firewall logs.
