There has been an update to NTP to ntp-4.2.8p12 and I've compiled a version for Windows (XP up to Win-10-32/64) here: http://www.satsignal.eu/ntp/x86/index.html Note that you might need to update your OpenSSL too, details on that Web page. Thanks to @NTP for the update. -- Cheers, David Web: http://www.satsignal.eu
