Thanks for the clarification. I can see the logic of the Unix way here.
As I'm looking into the general question of how ntp behaves at Windows
startup, I now have another question.
Save scenario as above, and I'm reporting errors via the Event Viewer.
I am experimenting with a PC which starts up very quickly, so that ntp can't
resolve its server addresses, giving rise to messages like "couldn't resolve
`2.us.pool.ntp.org', giving up on it'. In the Event Viewer, these are
flagged as Errors, and indeed ntp isn't doing anything very useful, as it
was unable to resolve any of the server addresses when it started. So far so
good, and I understand what is going on.
However, from the point of view of Windows, the "NTP service" is still
running, ie this doesn't count as a "service failure". So my question is:
why is a non-functional ntp process continue to run?
If it exited, then the Windows service manager would be aware that something
was wrong, and it could automatically restart the service.
I hope this question makes sense.
