Great idea.  thanks for the tip.  Although query logging does not log
nxdomain errors as such, it gives some good hints as to the problem.

We are primarily a Windows shop.  If you connect to another Windoows box
via unc path, dns is not consulted.  Connecting to other Windows boxes in
other ways e.g., rpc or if a browser is configured to use a proxy server,
dns is consulted.  In my naivete I thought I could get by without putting
all my Windows hosts in dns.  I guess I can if I don't mind lookups that
are not in my dns databases.

I noticed also that if you mistype a domain name, in a url, for example,
dns trys to resolve the name, which surely results in an nxdomain error.
Then, to add insult to injury, my Windows resolver appends my domain to
the non-existing domain and logs another nxdomain error.

Thanks again.
