Assuming you are working at present with a Win2K + Samba setup, and are
perfectly happy and content with the way it is going, should it not be
incumbent upon you, according to the general principles of Due Diligence -
which regularly scrap companies that ignore them - to ask Microsoft why?

Co-incident with our discussion about the hz_timer, I just saw this come
in from the Bochs list. Not quite the same issue, but along the same
lines.
Excess CPU usage by virtualised environments seems to be an issue in more
places than we might expect.

I think it's a question of whether Win2003 retains the ability to operate in
mixed-mode (ie, partial AD, partial domain). Samba 2.x still emulates a NT
domain, and if they've dropped support completely for NT domains in Win2003,
then they're right.
That said, it would seem to be fairly stupid to
The bottom line is that MS is making an assumption that to do the
consolidation that we will have to convert to W2003 AD and our plans
actually call for W2K AD in mixed mode. But trying to convince them of

It occurs to me that I may have been wrong when I speculated that SCO wants to be
bought by IBM. I am starting to think that SCO just wants IBM to support AIX (and pay
more royalties). It sounds a lot like IBM is planning to drop AIX, which would hurt
SCO.

Now that you mention it I had been told that the next version of Windows would not
support mixed mode. I know that next is relative, but I suspect that Win2003 is the
next version I was told about.

It sounds to me like Microsoft is correct. I think you said before that you had
