My working system is W2K :-[

I know. There's another version from a Russian developer called WinObjEx and
I am currently working on a reduced Delphi version for an article about the
native API.

So no doubt. You are right.

IIS is included (it replaced the PWS - Personal Web Server - from Windows
9x/Me, just with limitations, e.g. 10 connections max.) in W2K/WXP (but not
installed by default), that's why I ask.

They are :) - but as I said as a shell namespace extension not allowing for
mounting them to directories of DOS drive letters. And you had to install it
explicitly.

Hehe :) ... would you really like this ... the word "malware" pops into my
mind ...

WebDAV is a meta-filesystem for sure, but the access to it is not
necessarily achieved via filesystem driver. Access of Midnight Commander to
an FTP URL does also not require a filesystem driver (just as an example).

Definitely. That would be a perfect remote door into kernelmode of any XP
machine. There's surely a usermode component.

Thanks for the information.
