WebDAV, the core Windows 2K team didn't.
Make that the overly simplified and cynical explanation.. :)

IMHO, The win2k team wasnt opposed to DAV, they just werent willing to sign
up to
build a new redirector for win2k.   That isnt saying anything abouit DAV,
they really
had plenty of things to do before shipping win2k.   There were a bunch of
that ended up in XP that were originally on the win2k schedule way before
was suggested but were cut.
Your comment indicates that the win2k team didnt like DAV.  Even if that is
in the book
you mention, I dont remember experiencing that sentiment from the people I
with in NT networking.
BTW:  my original explanation of how the XP DAV worked came from one of
people who were in the NT networking team.

An OOps..
in my haste, I definitely forgot to include the office/rosebud team in who
did a lot of work to make DAV happen for IE5/office2000...  They did a lot
of work.

Many of you will also remember Yaron Goland, who personally emitted a great
amount of hot air (as you know he can) preventing DAV from being cut
numerous times.
