in the client you specify multicastclient, but in the server config you do
NOT specifiy: broadcast 224.0.1.1 

So are you sure that the server is spitting out a multicast on 224.0.1.1?  
Thanks for your response, but I'm still looking for some broadcast
client/server specific insight.  What kind of ntpq -p output do you have
on the server and clients?  Broadcast and multicast with ntp are very
similar in configuration.. but the fact that you don't even specify
"broadcast" line in the server config is a bit strange.
