Windows does not include NTP by default. It runs Microsoft's implementation of SNTP, a stripped down version which lacks many of the features and safeguards included in the full implementation. Microsoft's version, unless it is very recent, does not comply with RFC-2030, the standard for SNTP. Systems running SNTP are not considered acceptable as servers unless they are connected to a hardware reference clock, such as a GPS Timing Receiver. You can get a Windows version of NTP but there's no point if you insist on operating without either an internet server or a hardware reference clock. You can "require" anything you please but the software is not obligated to provide it. If you client does not care about having the correct time you could configure the local clock on the Linux system as a "reference clock" as follows: In ntp.conf, put: # # Declare the local clock to be the clock of last resort. # It will be used to serve time in the absence of any other. # server 127.127.1.0 # Local clock, unit 0 fudge 127.127.1.0 stratum 10 # Ensure that no one with a choice # will believe this clock!! If you MUST use the Windows system as the server, you will have to install NTP on it. There are three Windows versions available Windows NT / 2000 / XP / Windows .NET Server 2003 http://norloff.org/ntp/ - Maintained by TerjeMathisen ([EMAIL PROTECTED]) Windows NT 4, Windows 2000, Windows XP, Windows 2003 Server - English - http://www.meinberg.de/english/sw/ntp.htm Maintained by HeikoGerstung and http://www.meinberg.de/german/sw/ntp.htm Windows NT 4, Windows 2000, Windows XP, Windows 2003 Server - German - Maintained by HeikoGerstung _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
