OK.  This is why this configuration is NOT simple!  My original 
comments, and my reply to Michael, are based on not using prefer.  You 
have used two prefers, and I would have to check the source code to see 
how ntpd handles that.  It may average the two, or it may stop on the 
first prefer peer that is still valid.
