Terminal Server Creates Separate NTVDM for Each 16-bit Process Created from a Client Session

ID: q216995

The information in this article applies to:

Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

When using the Terminal Server Edition (TSE) client to connect to a Microsoft Terminal Server computer and the user runs an application written in 16-bit code, Terminal Server will start separate NTVDMs for each instance of the application started. This is not the expected behavior of a 16-bit application and may cause behavior problems for the 16-bit application. This behavior will only manifest itself when the 16-bit application from the TSE remote client; if the application is started locally on the Terminal Server, the 16-bit application behaves normally.

RESOLUTION
