I would expect Windows NT/2000 might be susceptible as the shell is
supposedly POSIX compliant; the normal commands one might use are
different (more VMS-like), of course.  There is a Unix option for NT
that adds many common Unix tools including Korn Shell.  In either case
it's probably just as much an issue.  It's mostly trivial to find which
OS is on the system by examining TCP/IP sequences.  Windows practically
shouts it's presence on TCP/IP.  One with intent could figure out easily
either by brute force or an educated guess.

The Win9x shell shouldn't have any issues.  It's almost useless with
direct access to a prompt.
