On the TP_STARTED call, an APPC application may fail and the following error message may occur:
Primary Return Code = F004 (AP_COMM_SUBSYSTEM_NOT_LOADED)
Secondary Return Code = 00000000 (no applicable subcode)
The APPC Programmer's Guide in the online SDK documentation describes the F004 error as follows:
A required component could not be loaded or has terminated while processing the verb. Thus, communication could not take place. Contact the system administrator for corrective action.
CAUSE
This error can be caused by the application calling an incorrect version of the Wappc32.dll file. This file is installed with SNA Server in the Sna\System directory.
RESOLUTION
If there is a duplicate Wappc32.dll file on the computer in the \WINNT\System32 directory for example, delete or rename it.
