[ntp:questions] Having trouble with an NTP server configuration

Hello,

I'm trying to set up an NTP server on an RHEL 6.1.
Synchronization via *ntpdate *seems to work fine and apparently everything
works OK seing it as a *client*, however, the server itself its not
working, it shows a *stratum* of 16 and never decreases.

My */etc/ntp.conf *is as follows:
restrict 127.0.0.1
restrict -6 ::1
restrict 192.168.75.21  mask 255.255.255.0 nomodify notrap
server 192.168.50.233
fudge   127.127.1.0 stratum 10
driftfile /var/lib/ntp/drift
keys /etc/ntp/keys

The output of diagnostics command is:

[root at AdminSoa ~]# ntpq -p

I aslo find it weird (not sure if its important) that when I restart the
service, it isn't trying to synchronize. Anyone can give me a hand on this?
I've tried several different things and nothing... Thanks!
