SYMPTOMS
Normally, an administrator can use the registry to set compatibility flags for specific applications being run on Windows Terminal Clients. For example, adding the following registry key and value to HKEY_LOCAL_MACHINE on the Terminal Server will force the application, in this case NTVDM, to use the Terminal Server's Windows System folder, instead of the user's Windows folder:

   Software\Microsoft\Windows NT\CurrentVersion\Terminal Server\Compatibility\Applications\    KEY: NTVDM   VALUE: Flags  reg_dword  0x400				

This setting can be used to force all applications running within NTVDM to use the _Default.pif file on the server for custom settings, rather than requiring the administrator to copy the _Default.pif file to the Windows folder of each user.

After you add the Application Compatibility Flag to the registry, the application does not respond to the flag.
