How do I setup up XP to prevent the execution of 16 bit
exe files and/or dlls?

Hi Steven,

Thanks for your reply. Unfortunately, restricting
command.com and cmd.exe does not necessarily prevent 16-
bit exes from running.

I want to prevent 32-bit programs from doing a
CreateProcess to launch a 16-bit exe.

Regards,
Peter

Hi Peter,

We also need to restrict the Ntvdm.exe (Virtual DOS Machine). Then, the
16-bit application won't run.

Thanks for using Microsoft News Group!

I have followed the instructions in article 310791 to the
letter and it has not stopped anything.

I used gpedit and added additional rules (Path type,
Disallowed) for
c:\windows\system32\cmd.exe
c:\windows\system32\command.com
c:\windows\system32\ntvdm.exe

I can still run a Command prompt and call 16-bit programs
from a 32-bit program. Re-booting did not help.

I also tried removing the other paths in the Additional
Rules list in case they were over-riding my settings but
that had no effect.

Any help would be appreciated.

Regards,
Peter

Following my earlier posting today:

I have succeeded in getting it to not run command.com and
cmd.exe. However, Disallowing ntvdm.exe has not stopped
it running DOS programs or executing (via CreateProcess)
a 16-bit program from within a 32-bit windows program.

If I run a DOS program, ntvdm.exe is in the Task
Manager's list of running processes.

Any help would be appreciated.

Regards,
Peter

Hi Peter,

If the user is the local user, we also can set the NTFS permission of the 3
files of the user. We can remove all permission of the 3 files to the other
user.

Then, the other users are unable to run the 16-bit applications.

Thanks for using Microsoft News Group!

Sincerely,

Steven Liu
