-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft SNA Server, versions 2.0, 2.1, 2.11, 2.11 SP1, 3.0, 3.0 SP1 
-------------------------------------------------------------------------------


SYMPTOMS
========

The CPIC function Extract_Partner_LU_Name (CMPELN) returns only the partner LU
alias, not the fully qualified network name if the conversation is initiated by
the remote system.

CAUSE
=====

The Microsoft SNA CPI-C Programmer's Guide states that the CMEPLN() call returns
either the partner LU alias or the fully qualified partner LU name, but it does
not specify what conditions determine which value is returned. If the
conversation is initiated by the remote system with CMACCP(), only the PLU alias
is stored. The fully qualified PLU name is returned to the CMEPLN() call if the
conversation is initiated by the CPIC application itself (the CPIC application
issues the cmallc), and if the CPIC side information is configured with a fully
qualified PLU name, or if the application specifies a fully qualified PLU name
using the CMSPLN() or XCMSSI() functions.

RESOLUTION
==========

To resolve this problem, obtain the hotfix mentioned below. In the hotfix, the
function has been modified to always return the fully qualified partner LU name
unless the CPIC side information (the CPIC Symbolic Destination Name being used)
for an outgoing conversation has only the Alias configured in the SNA Admin or
Manager.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft SNA Server versions
2.0, 2.1, 2.11, 2.11 SP1, 3.0, and 3.0 SP1.
