On the subject of Windows generated useless traffic, I have been woking with
RIPE to look at how many queries to k.root-servers.net are for dud TLDs -
the majority of which are caused by Windows using the DNS to look up the
local NT domain name - requests of the form "FOO."

The results are somewhat scary - it seems that around 20% of all queries
are generated by this behaviour.  I can't give you any more info at present,
as we are still working on the data - it is literally something I am in the
middle of doing at the moment, but wanted to give a quick heads up to folks
in the light of this thread.
