After "service ntpd stop"

$ ntpdate clock1.redhat.com
Looking for host clock1.redhat.com and service ntp
host found : clock1.redhat.com

So the server is acting and responding here. You can test that your own.

Do you have a custom firewall and port 123 closed? I think the pin hole
mechanism from /etc/init.d/ntpd will only work correctly with the Fedora
rules being active (see the testing for "RH-Firewall-1-INPUT" in the
init script).
