Negative caching of DNS queries never expires?
Hi!
I was doing some tests with a samba 3.0.2a server set up to be a wins server
and to do dns proxy, and I have found that when you queried nmbd for a name
ahta was not on wins db or found on DNS, the negative response is cached
either for a really long time or forever, in such a way that even though you
add the name to the DNS, you won't get a positive answer out of nmbd
anymore.
I have tried solving this by lowering the minimum ttl in my soa as well...
