TITLE   :5250 Printer LU Hangs When Client-Server LAN Session is Lost
PRODUCT :Microsoft SNA Server
PROD/VER:WINDOWS:2.0,2.1
OPER/SYS:
KEYWORDS:

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

 - Microsoft SNA Server, versions 2.0, 2.1, on platform(s):
    - the operating system: Microsoft Windows NT 
-------------------------------------------------------------------------------


SYMPTOMS
========

If you are using a third party 5250 print emulation product over SNA Server and
the print emulator is stopped, or the client-server LAN session is lost, the
AS/400 printer LU session is not cleaned up properly. As a result, 5250 print
emulation product cannot reconnect to the AS/400 printing device.

CAUSE
=====

When the 5250 print emulator is stopped, a Deallocate(ABEND) negative response
is generated. If the LU6.2 session is in a receive state, the response cannot be
sent (according to LU6.2 protocol).

RESOLUTION
==========

To correct this problem in SNA Server version 2.1, install the SNA Server 2.1
SNA Server service update (NODEUP.ZIP) located on the following electronic
services:

 - On the Internet, the file is located on the Microsoft anonymous ftp server
   (ftp.microsoft.com). To download NODEUP.ZIP, change to the following
   directory:

   \bussys\winnt\sna-unsup-ed\fixes\nodeup

   The NODEUP.ZIP file must be uncompressed using PKZIP 2.04g or later, using the
   following command:

   pkunzip -d nodeup.zip

A README file is included and describes how to install the update.

There is no update available for SNA Server 2.0.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products that are
listed at the beginning of this article.
This problem was corrected in SNA Server 2.11.

MORE INFORMATION
================

If the application ends or the SNA Server client-server LAN session is lost, SNA
Server (with the SNA Server 2.1 SNA Server service update installed) treats this
condition as though the transaction program (TP) issued a TP_ENDED(HARD). The
session unbinds immediately instead of trying to deallocate the conversation.
