When asking a question like this, you really need to supply more 
details.   What hardware are you talking about; PC, Mac, Sun Sparc, DEC 
Alpha. . .. .   What O/S and what version?  What version of NTP?  Did 
you build NTP from the distribution or are you using a precompiled 
version?  If it's precompiled, where did you get it; e.g. came with the 
O/S, downloaded from ....?
