Q182267: [MC_]ALLOCATE May Return Sense 00000805 Instead of 08050000

Article: Q182267
Product(s): Microsoft SNA Server
Version(s): WINDOWS:3.0,3.0 SP1,3.0 SP2,4.0

SYMPTOMS
========

If a Win32 APPC program calls [MC_]ALLOCATE and the request fails on an
Intel-based server, in some instances the returned sense_data may not indicate a
valid sense code. For example, if session limits are exceeded, APPC returns a
sense code of 0x00000805, instead of 0x08050000.

CAUSE
=====

The SNA Server APPC interface (Wappc32.dll) is not properly formatting the
4-byte sense_code returned parameter on Intel systems. Because APPC is
implemented in a platform-independent fashion and Intel systems store
double-word values in byte-inversed order in memory, the APPC DLL is not
properly formatting the sense code before returning to the APPC application.

STATUS
======

Microsoft has confirmed this to be a problem in SNA Server 3.0 (all service
packs) and SNA Server 4.0. We are researching this problem in SNA Server version
3.0 and will post more information here in the Microsoft Knowledge Base as it
becomes available.

This problem was corrected in the latest SNA Server version 4.0 U.S. Service
Pack. For information on obtaining this Service Pack, query on the following
