But I don't quite understand what you meant about "let ntpd take it from here" or "if it started out close"... (I am French and maybe you're using a figure of language I don't understand...) Are you running with an elevated securelevel? No the Secure Level is -1... But I've found the beginning of a solution... It doesn't come from ntpd but from the Windows Time Server. When configured to sync with its internal clock, the NTP Server IP packets that goes to the client contain strange values (rootdispersion, etc.) that are higher than expected. Thus, ntpd doesn't consider the Windows Server as a reliable source. But once the windows server configured to sync with an external source, it works! The IP packets generated from the windows server begin to look like "real" and reliable answer to ntpd... I'm working now on a correct configuration of the Windows Server. Thanks again to all!
