SYMPTOMS
When you use the Microsoft Windows NT Multitasking MTA (NT MMTA), and you create and start a service, you will get the following error when you try to monitor the instance:

ERROR OS/2 ERROR CODE 38



CAUSE
This error occurs because the Windows NT OS/2 subsystem is trying to launch the MS-DOS or native OS/2 version of EXTERNAL.EXE or DISPATCH.EXE as a service.



RESOLUTION
In the Microsoft Mail Service Manager, Edit Service dialog box, ensure that the Executable Path parameter displays the correct path to the EXTERNAL.EXE or DISPATCH.EXE file that was included with the NT MMTA. These files are normally located under the \MAILEXE\EXTERNAL.NT or \MAILEXE\DIRSYNC.NT subdirectory.



MORE INFORMATION
The MS-DOS version of EXTERNAL.EXE and DISPATCH.EXE are not bound applications. This means full functionality is available only under their native environment, and somewhat limited functionality in other environments, such as the Windows NT OS/2 subsystem. As a result, the Mail External program and Dispatch will not operate as a service under the Windows NT OS/2 subsystem.

For additional information about the supported options of the Mail External program under Windows NT, please see the following article in the Microsoft Knowledge Base:

118620 Support of EXTERNAL.EXE under Windows NT

A brief explanation of "Error OS/2 error code " can be found in the Windows NT "Resource Kit" version 3.5 Volume 3, page 278.
