Hi,

Thank you for posting here!

I am sorry for the delayed response due to weekend. Please understand that
the newsgroups are staffed weekdays by Microsoft Support professionals to
answer your systems and applications questions. Your understanding is
greatly appreciated!

For your description, I understand that you get the "NTVDM encountered a
hard error" when you run applications like TrendMicro or MS-DOS. if I am off
base, please don't hesitate to let me know.

Based on my research, the issue is a Server issue. I suggest that you post
this question into the microsoft.public.windows.server.general newsgroup.
you can find the newsgroup in following link:

http://www.microsoft.com/technet/community/newsgroups/dgbrowser/en-us/default.mspx?query=microsoft.public.windows.server.general%20&dg=&cat=&lang=en&cr=US&pt=&catlist=73789D5F-4DB8-4D45-81E2-42064A655D3D&dglist=&ptlist=~Microsoft%20Windows%20Server

The reason why we recommend posting appropriately is you will get the most
qualified pool of respondents, and other partners who the newsgroups
regularly can either share their knowledge or learn from your interaction
with us. Also, this is to make sure that the responders can better track
the problem Thank you for your understanding.

I also would like to give you some information about the issue.

how to configure to prevent access to 16-bit applications in Windows Server
2003

Requirements: At least Microsoft Windows Server 2003

Location: Computer Configuration\Windows Components\Application
Compatibility\

Description:
Specifies whether to prevent the MS-DOS subsystem (ntvdm.exe) from running
on this computer. This setting affects the launching of 16-bit applications
in the operating system. By default, the MS-DOS subsystem runs for all users
on this computer.

You can use this setting to turn off the MS-DOS subsystem, which will reduce
resource usage and prevent users from running 16-bit applications. To run
any 16-bit application or any application with 16-bit components, ntvdm.exe
must be allowed to run. The MS-DOS subsystem starts when the first 16-bit
application is launched. While the MS-DOS subsystem is running, any
subsequent 16-bit applications launch faster, but overall resource usage on
the system is increased.

If the status is set to Enabled, ntvdm.exe is prevented from running, which
then prevents any 16-bit applications from running. In addition, any 32-bit
applications with 16-bit installers or other 16-bit components cannot run.

If the status is set to Disabled, the default setting applies and the MS-DOS
subsystem runs for all users on this computer.
If the status is set to Not Configured, the default applies and ntvdm.exe
runs for all users. However, if an administrator sets the registry DWORD
value HKLM\System\CurrentControlSet\Control\WOW\DisallowedPolicyDefault to
1, the default changes to prevent all 16-bit applications from running.

Note
This setting appears in both Computer Configuration and User Configuration.
If both settings are configured, the Computer Configuration setting
overrides.
ADM File: system.adm
