[ntp:questions] NTP client configuration

We are using Meindberg NTP client and server.

Our configuration is:
- 1 Computer under windows that is server
broadcast minpoll 4 maxpoll 4 iburst
disable auth
- several computer under linux + computers under windows, client of this 
server minpoll 4 maxpoll 4 iburst
disable auth

My problem is the following:
Mainly on windows computer, sometime, depending what the computer is 
doing, there is a big offset between clients and server.
("Big" for me is more than 500ms).

I would like to know if it is possible to setup client so as soon as he 
see offset>500ms, then client do a "fast" synch. (STEP).

Another way to solve my problem could be for me, to modify the source 
code of my application in order to get this "offset" information inside 
my code (C or C++ langage). then I could add this offset to the time of 
the computer in order to be as much accurate as possible during the time 
the offset is bigger than 500ms.

Do you have any solution?
