The information in this article applies to:

   - the operating system: Microsoft Windows NT

SYMPTOMS
========

If the installation path of the SNA Client is longer than 64 bytes, the Windows
95 3270 applet (Win3270.exe) returns the error message

  FMIS3270.DLL not found

and fails to connect.

CAUSE
=====

When the 3270 applet builds the full path to the FMI driver, a maximum path of
64 bytes is allowed.

RESOLUTION
==========

The 3270 applet FMI call now uses MAX_PATH and is not limited to a 64-byte path
name.

STATUS
======

Microsoft has confirmed this to be a problem in SNA Server 3.0 and 3.0 Service
Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0
U.S. Service Pack. For information on obtaining this Service Pack, query on the
