What I want to state is: somebody has a Windows domain and is asking how he can check if its time is similar to some external ntp server. Windows provides the w32tm command with the /monitor flag that accomplishes exactly that. The user did not ask how he could get better time, he only wanted to see what is going on. I don't think it is necessary to project one's own expectations about time accuracy on that question and suggest him to install a different NTP daemon. He probably is not even able to do that, because the domain sync is done on the domain controller, where he may not be able to install software. But he can issue the w32tm command on his workstation and monitor the situation (at least when NTP is not blocked in the firewall, which it now seems to be). So, let's just answer the questions asked. Without religiously trying to convert everyone to different software. That can be done later, when the followup question "my time is 0.3 seconds off how can I improve that" is asked. Maybe de OP is not interested in milliseconds or seconds, but sees the domain time being off by minutes. That happens, you know. (especially when the firewall blocks NTP even for the domain controller) _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
