    My DNS server seems to be suffering from intermittent failures to respond to requests for a newly added subdomain. The service status seems to say everything is fine but every so often requests for the new suddomain don't resolve (its happens a number of times a day).

    My secondary dns is a bit out of sync at the moment so I need to be able to find out why my dns isn't responding to every request for the suddomain.

    I checked the service log and I can only find 1 entry for named service wasn't running but it restarted soon after.

    Is there a way to log all DNS requests for a domain/subdomain for 24 hrs so I can see whats happening to requests?


    The subdomain won't respond to pings either but the domain will

    Is there a particular log file I should consult to see if DNS is encountering errors? The service status doesn't seen to saying anything helpful

    Thanks,
    I'll read up on it but right now am thinking it could be too much strain on the server

    When using BIND for the DNS server daemon, the following system log file may be checked for potential clues and error detail:
