Windows 2003 DNS server's IPv6 support

[Frank Bulk]

Thanks.  I did that already, and restarted the service, but the iterative
commands are still IPv4.  I also verified that EnableIPv6 = 1 is in the
registry, too.

On your Win2K3 Server, run the following command:

dnscmd /config /EnableIPv6 1

That will allow DNS to use IPv6 instead of IPv4.  In Windows Server 2008 and
2008 R2, that command isn't necessary; they allow v6 or v4 communications by
default.

an IPv6 address, but won't initiate requests to the root servers, etc on
IPv6.  When I did a v6 dig from a *nix box while doing a packet capture on
the Windows 2003 server, I saw the UDP request for onlyv6.com, but the DNS
server's queries to the root server for the NS records and all subsequent
queries were v4.  The result was "no servers could be reached".

Can anyone else confirm this behavior?  Is that resolved in Windows 2008?
