Actually, there is one other advantage in using TCP:
I frequently use a cellular link (GPRS). I use it on moving vehicles like
trains and in areas where 1000+ msec latency is standard.
I've searched around windows for the longest time for a way to fix badly
broken negative caching behavior, but have realized that if there were
some way to tweak the resolver to do TCP-only, I would at the very least
be at the advantage of a connection-based protocol instead of at the mercy
of a negative cache.
That said, I could certainly install BIND and point my resolver at
localhost, but does BIND support an option to force TCP? (Even assuming
that to prevent the firewall issue, I set forward-only so I wasn't
randomly trying the commonly blocked TCP port everywhere).
