SYMPTOMS
The Windows 2000 Server Resource Kit documentation for APPSEC.EXE states that to allow users to run 16-bit applications, you will need to add NTVDM.EXE to the authorized lists of applications. However, attempting to add NTVDM.EXE to the Authorized Application list, using the Add Authorized Application dialog box, will not add NTVDM.EXE to the list.



CAUSE
It is not possible to add NTVDM.EXE to the list using the Add Authorized Application dialog box.



WORKAROUND
To allow users to run a 16-bit applications, add the 16-bit application to AppSec. This will automatically add NTVDM.EXE as well as other files that are required to run a 16-bit application (e.g. WOW).

To verify that NTVDM.EXE has been added, exit the AppSec utility and then re-launch it.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
The following information in the Resource Kit documentation for APPSEC.EXE is incorrect.

&quot;The Application Security tool can only be used to restrict 32-bit applications. By default when AppSec is enabled users are restricted from running any 16-bit applications. To allow users to run all 16-bit applications, the administrator can add ntvdm.exe to the authorized list of applications.&quot;

Note: This documentation is included in both the Windows 2000 Server Resource Kit and the Windows 2000 Professional Resource Kit. However, the AppSec tool is included in the Windows 2000 Server Resource Kit only, and is not included in the Windows 2000 Professional Resource Kit.
