Yes, both NT4 and W2K return the same value when you call function 30h of 
Int 21h or subfunction 6 of function 33h of Int 21h.  That's the crux of 
the problem: they both identify themselves as DOS 5.10 (IIRC).

You should be able to get the Windows version with Int 2Fh/AX=1600h, but 
I think NT4 and W2K return the same result there as well.
