This would definitely pose a challenge if my IP changed.  So ntpd resolves 
the domain once, then uses the resulting IP address until the next reboot or 
service restart, correct?

My server is on a network behind a router, and the router and modem never 
get turned off.  Could this be why I keep the same IP for extended periods? 
Comcast told me once that their lease period for the dynamic IP addresses is 
one week, but almost always lease the same IP continuously.  I was going to 
call Comcast last night and inquire about purchasing a static IP (if that's 
even possible), but didn't get around to it.

All that I know about this server is what I gather from here: 
http://ntp.isc.org/bin/view/Servers/TimeNwNistGov.  According to that link 
the server is not running a Windows OS (surprising).   Maybe Microsoft 
allowed the government to come in and set up a server using their network. 
You may be right about it being overloaded, as under 'ntpq -p' it's always 
flagged with the hyphen (-).  I was considering replacing it with a 
different server.  I chose it only because of its proximity to me, and low
