Oliver,
Thanks for the additional details.
Based on this I think it is clear that this is not a bug in puppet. Your
Windows servers should not be responding SERVFAIL to AAAA queries. They
should be responding with NOERROR and no answers. I think that bind is
probably doing the right thing according to the specification here,
although I'm not completely sure.
It seems to me that the behaviour that you're seeing is an unfortunate
consequence of your Windows DNS servers not supporting IPv6 properly, by
failing when they are queried for IPv6 addresses. Perhaps there is an
option somewhere to turn it on, or an option in bind to work around
broken upstream DNS servers?
Since my conclusion is that this is not a bug (neither in puppet nor
bind) in Ubuntu, I'm marking this bug as invalid. However, I may be
wrong. If you can point to an authoritative source that states that bind
is supposed to respond differently when getting a SERVFAIL upstream,
then please point to that and change the bug status back to New, and
we'll retarget the bug at bind.
** Changed in: puppet (Ubuntu)
Status: New => Invalid
** Summary changed:
- Ubuntu 12.04 resolving hangs when querying AAAA records against BIND (Ubuntu
10.04) DNS servers
+ BIND (Ubuntu 10.04) DNS servers do not respond when forwarding for upstreams
which return SERVFAIL
