Agreed it shouldn't make much difference. I mean if clients
repeatedly ask for things that don't exist, then something
else is wrong.

Guess with all these damned dynamic updates, I'd like the
ability to add a W2K box entries to the DNS faster than 3
hours (After clueless admin plugs it in, and finds "we don't
do dynamic updates"). Then again anything that delays the
march of Windows, even if only for 3 hours....
