I'd guess these are bugs in the NT DPMI host, but please tell more
about what programs crashed and what were you doing when they did.

Please do. Sometimes, this is all that is needed to find a
work-around or a solution.

Emacs is known to crash on NT, and it has been established that this
is a bug in NT DPMI host. I don't know about other programs, but you
didn't say which programs crashed.

You can't do this on NT, since it has its own DPMI host built-in, and
even if you were to succeed in installing PMODE, DJGPP programs won't
use it because DPMI services are already available on NT when a DJGPP
program starts.
