WinINet Error 12031 is "ERROR_INTERNET_CONNECTION_RESET - The connection
with the server has been reset"

In other words, the connection to your server was lost (e.g. the firewall
was resetting the command channel connection established on port 21; the
reset happens at the TCP/IP stack level). In most cases it caused by the
firewall or the wonderful buggy anti-spyware / anti-virus products.
