PRB: 16-Bit App Launched from Service Always in Own VDM

 * }

Q154115

-

The information in this article applies to:


 * Microsoft Win32 Application Programming Interface (API), used with:
 * the operating system: Microsoft Windows NT, versions 3.51, 4.0
 * the operating system: Microsoft Windows 2000

-

SYMPTOMS
When a 16-bit Windows application is launched from a Windows NT service or from a 32-bit process that was launched from a service, the Windows application is always launched into its own separate VDM (Virtual DOS Machine). 16-bit applications launched by other 16-bit applications always run in the same VDM.

STATUS
This behavior is by design.
