    How do we get the slave server to sync the zones from the primary server? When we click "Synchronize DNS Records with Primary Nameserver" it says "Rebuilding DNS Zones List from master server .....Rebuild Complete". The problem the zones do not get updated.

    Login to your server,

    cd /var/named

    ls -l

    Are all the zones there? Sometimes running

    /scripts/dnstransfer

    several times has been necessary to completely transfer all zones over to your server from the primary name server.

    After that when all zones have transferred over to your server the secondry name server zones should update at the intervals that they are set to refresh from master zone.

    That may be set at 4 hours, you can reduce that by reducing the refresh time. Hope that helps.

    So if the TTL is set to 4 hours and a subdomain is created, the secondary will not see the subdomain for 4 hours?

    Basically yes, up to 4 hours.

    If your ISP has the dns in its cache, then the changes can take up to 4 hours, if not, then the change can be instant to you.
