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

Is it possible that one of the authoritative servers for .us is
unreachable/down at the moment, at least from name server 24.197.96.16's
point of view? 198.6.1.2 gives similar results.
Thanks again,

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/
