This, in conjunction with fixing my broken "restrict" statements did the trick. Basically, when I set up ntp years ago on my machines, I was not running any local ntp server, so they all hit the public ntp server and I basically had my machines set so that they would not synchronize each other. Whem I setup the ntp servers on my network which were to synchronize from the public ntp servers and then provide ntp service to my other servers and workstation, I just copied an ntp.conf from one of the workstations. Of course, this made it so that the clients wouldn't synchronize since I had use the restric keyword to prevent it. A bit of reading through the documentation let me figure out why what I was doing with that was wrong. So bascically, my workstations and servers have not been getting the benefit of NTP for nearly a year now. It's good to be back on track.
