When you attempt to open a 16-bit Microsoft Exchange Electronic Forms Designer (EFD) form with Microsoft Outlook 97 running inside a Terminal Server client window, you may receive the following error message:
If you receive this error message, one or both of the following events are written to the Terminal Server computer's system event log:
If you run Outlook 97 on the console of the Terminal Server computer, you can open the same 16-bit form without the error message being displayed.
In some situations, when the first 16-bit program to be run in the current user's logon session is invoked using COM, the system may create a new or additional Windows NT Virtual DOS Machine (NTVDM) that runs in the local system's security context, instead of in the security context of the logged-on user. Local system does not have the required permissions to load the form, and the error message is displayed.
To resolve this problem, obtain the latest service pack for Microsoft Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Ensure that the Wowexec tool (Wowexec.exe) is running in the context of the logged-on user before you attempt to load a 16-bit form, using either of the following methods:
- Click Start, click Run, type wowexec.exe, and then click OK.
- Run Wowexec.exe from the user's logon script.
Microsoft has confirmed that this is a problem in Microsoft Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Microsoft Windows NT Server 4.0, Terminal Server Edition Service Pack 6.
