The information in this article applies to:

- Microsoft SNA Server, versions 2.11 SP1, 2.11 SP2, 3.0 SP1, 3.0 SP2, 3.0 SP3, 3.0 SP4, 4.0, 4.0 SP1, 4.0 SP2, 4.0 SP3, on platform(s):
   - the operating system: Microsoft Windows versions 95, 98 
-------------------------------------------------------------------------------

SYMPTOMS
========

On Windows 95/98 computers, the 5250 and 3270 applets may not find the SNA
Server when the SNA client configuration is set to Local mode (locate servers by
SNA Sub-domain). A TCP/IP error 121 may also occur.

CAUSE
=====

Local client mode (TCP_IP transport) is unreliable on a busy network because the
client does not wait long enough for SNA Servers to respond to its sponsor
request broadcast.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for SNA Server 4.0. For
additional information, please see the following article in the Microsoft
Knowledge Base:

  Q215838 How to Obtain the Latest SNA Server Version 4.0 Service Pack

WORKAROUND
==========

Set the SNA client configuration to Remote mode (locate SNA Servers by name) and
enter the sponsor server name (or IP address).

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 first corrected in SNA Server 4.0 Service Pack 4.
