[ntp:questions] synchronization distance

[David L. Mills]

David,

I had no idea somebody would try to configure current NTPv4 with a poll 
interval of a week. The current maximum allowed is 36 h. Windows ex box 
at one time did use symmetric active mode in error, but I understand it 
now uses client mode as specified. In any case, Windows NTP (not NTPv4 
running in Windows) is cheerfully ignorant of most NTP parameters, 
including synchronization distance, and that is peachy keen as long as 
the users are satisfied.
