Content-Type: text/plain Content-Disposition: inline Content-Transfer-Encoding: binary MIME-Version: 1.0 X-Mailer: MIME-tools 5.507 (Entity 5.507) RT-Send-CC: X-RT-Original-Encoding: iso-8859-1 Content-Length: 394 DNS_QUERY_RETURN_MESSAGE does not seem to do anything (the docs say it isn't supported in W2K, but they might actually mean it isn't supported in W2K or later). After discussion with dochelp, it doesn't appear that there's any future-proof way to use DnsQuery() with new record types. So this bug seems unfixable for now, short of including or depending on a complete DNS implementation.
