Hello Simon,
When I run the ntpq -p server1 command I get an
"timeout, nothing received" so I tried the same command on 5 other machines
that are currently working fine and I get the same error so I am unsure why
that is. The tcpdump command is showing no such file or directory, are you
sure the syntax is correct?
Regards

Please respond to

Well as the configuration does work on other hosts, we don't going to
focus any further on this.
But what's about the output of ntpq -p <ntp source server>
In your example like: ntpq -p Server1
What does tcpdump telling you:
Run # tcpdump -i <intergace> -vvv port 123
Is there any activity reported?
Cheers,
Simon
