Since you've affirmed my first instinct I'll retract what I said about DDNS and concur with your statement. DDNS in Windows didn't exist before Windows 2000 (as AD also didn't), and Win9x operating systems didn't have services as I recall it, though. Admittedly, I thankfully haven't used a Win9x OS in a very long time. -Vinny > --- > () ascii ribbon campaign against html e-mail > /\ www.asciiribbon.org > > > >
