NTP not working since power cut

Hi all, we suffered a power cut late on Friday and since then have been unable to get NTP working on our loadbalancers.

I've restarted the NTP daemon and when running: ntpq -np command I get the following:

[root@LTM1:Standby:Changes Pending] config  ntpq -np
localhost.localdomain: timed out, nothing received
***Request timed out

Does anyone know what might be causing this?

Thanks in advance,

Ant

    Ok, slight change... Now it is returning:

    [root@LTM1:Active:In Sync] config  ntpq -np
No association ID's returned
[root@LTM1:Active:In Sync] config  ntpq -p ntp0.net.strath.ac.uk
Temporary failure in name resolution
[root@LTM1:Active:In Sync] config  ntpq -p 143.210.16.201

    Ok, the answer to this was that our DNS server has moved to a different zone on our internal network so it couldn't resolve anything after the reboot.

     

    All sorted now though. Thanks for your assistance.
