"The reason why it's sending the query over and over is because the DNS server is returning a DNS response of RCODE: 2 (ServFail), which is not a normal response. It indicates a server misconfiguration. If the server were to return the standard RCODE: 3 (NXDOMAIN) response, then mDNSResponder would stop sending queries. It's still a bug in mDNSResponder that it's not handling the ServFail very well, but it explains why only a few people are seeing this issue. Most people have DNS servers that return NXDOMAIN as the response." It seems this bug comes up with various updates to OSX. The simpliest solution it seems is to have only one dns entry on the macbook for the dns resolvers. With only one entry it'll time out even with the servfail being returned. I dunno what you are doing with this network, handing out free wifi or whatever, but changing the dhcp configuration so the connecting computers only get one dns server should work also. -bruce bje@ripco.com
