    It's been a bit, but I think that happens when you do not have a PTR for your. NS. dig -t NS against the zone, also?

        Amr_Ali For a PTR I believe you can configure that on the authoritative name server that particular PTR. I believe the NS issue would also be configured at the authoritative name server for that zone or sub-domain.
