Our DNS server (RedHat 5.2 Linux, Bind 8.2.1) was running correct, but now we are getting errors on the secondary NS: not authoritative for domain.nl, SOA query got rcode 0, aa 0, ancount 1, aucount 0 I don't kown what's going wrong, but some mail server refuse our mail at this time, so we have a big problem. I hope someone can help me. Eric Richter
