Servers just doen't work (after following the troubleshooting page)

Hi!
I am setting up two ntp servers. The two servers can synchronize their time, but it won't serve. I followed the instructions in http://ntp.isc.org/bin/view/Support/TroubleshootingNTP (remove restrict, check ntp port, check ntpd status, use online tools, no dhcp, no MS Windows) but so far it doesn't help.
Any ideas?
More information below:
Both server almost identical, Red Hat 7.3, kernel 2.4.20-28.7, ntp-4.1.1-1.
