Without knowing any more than the above, it's not possible to tell!

What version(s) of ntpd are you running?  Which operating systems are 
you running them on?  What hardware?

My first guess would be that ntpd is not running at all on one or more 

How about posting the output of "ntpq -p" for the affected machines?
