I remember running into this one a long time back, so I investigated
IBM's site and then found this on Microsoft's web site:
===================================================
"Bad Fault in MS-DOS Extender"

This error message occurs when the fault handler dispatcher in
DOSX.EXE generates another cascaded fault while trying to
handle a protected-mode exception. This error is usually caused
by one of the following factors:

HIMEM.SYS is unable to control the A20 line.

DOS=HIGH is not functioning properly (related to HIMEM.SYS control).

The RAM, static RAM (SRAM), single in-line memory module (SIMM),
  or dynamic RAM (DRAM) chips are not functioning properly.

  You are running DR DOS.

The third-party memory manager is not configured correctly.

The EMM386.EXE NOEMS x=A000-EFFF line is missing from the Config.sys file.

You have an old, out-of-date ROM BIOS.

Your CMOS settings are incorrect.

Your Windows files are old or corrupted. To test this, create a new
directory on the hard drive, and install Windows in that directory.

Your disks are corrupted.

Your system is infected with the Form, Forms, Noint, or Yankee Doodle virus.
========================================================

It runs in my mind that when I ran into this before it was a case of the hard drive
infected with a virus.  You can check that easily enough, but do not disregard
the other options that Microsoft listed above.
