Mathias,

thanks for your answer, however i do have a fixed IP over   my box  
and as far as i understood Appel's artnum the prob, within MacOS X,  
arroses after the comupter sleep and wake again.

here is part of Apple's note :

and the advice is to use the "iburst" ntp server mode instead of  
"minpoll and maxpoll values"...

And someone suggest (Message-ID: <1hp3rsd.1q8bhyttf74wyN% 
xavier at groumpf.org> for french readers) that's Apple's file conf  
fault...

I do agree with him because they give a better approach.

Also it is well known on Mac OS X that after the computer going to  
sleep it's somehow hard to wake it up )))

Here i'm speaking from experience ;-)

best,

Yvon
