Thanks for your help, guys. Didn't know dig existed for windows. Several ISPs (charter.net, alter.net) are choking on .us queries right now, but AT&T's name server is working ok for me. Here's one failing on .us, but .com works fine: C:\temp\dnstools>dig @24.197.96.16 com NS ; <<>> DiG 9.3.1 <<>> @24.197.96.16 com NS ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 1940 ;; flags: qr rd ra; QUERY: 1, ANSWER: 13, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;com.

Thanks. Didn't have any *NIX boxes laying around to 'dig' any deeper.
i believe even windoze has dig at the command line, though i don't know in what directory it lies.
The web directory: http://www.isc.org/index.pl?/sw/bind/bind9.php or the ftp directory: ftp://ftp.isc.org/isc/bind/contrib/ntbind-9.3.1/BIND9.3.1.zip What is also very useful are the following two websites, so people can click around a bit and get nice pictures making everything crystalclear for them: DNSDoctor (which even supports IPv6 :) http://demo.dnsdoctor.org/ And of course DNS report: http://www.dnsreport.com/ Greets, Jeroen
