I have been marginally involved in the win2000 beta program, but not
enough to be 'the authority' on it.

To my knowledge WIN2000 is the child of the win95/98 and winNT union.
It has been VERY difficult for Microsoft to integrate the user features
of win95/98 into winNT, but the basic idea is they threw out a
significant portion of the win95/98 code, took the rest and merged it
with win2000.  winNT, in theory, is all 32-bit code, and is NOT built on
dos as was win3.1, win95 & win98.  This is one of the main reasons they
could not make a simple change from 95 to NT, much of 95 is written
expecting the DOS subsystem to be there.

winNT 4.0 includes programming which will allow you to run DOS programs
that do not overstep security (such as memory/device/port accesses
without the proper trusted device drivers).  So if your programs run
under both winNT 4  and win95/98 now, then they will very likely run
under win2000, although slower than they do under win95/98.  If you
can't run them under winNT now, you will have issues to resolve.

If your programs were written in C/C++ then it may be as simple as
changing a few things and compiling a Windows Console application under
Visual C.
