Q165440: Shared Folders Gateway Only Shows Root Directory

Article: Q165440
Product(s): Microsoft SNA Server
Version(s): WINDOWS:3.0
Operating System(s): 
Keyword(s): kbnetwork
Last Modified: 13-JUN-2001

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

- Microsoft SNA Server, version 3.0, on platform(s):
   - the operating system: Microsoft Windows NT 
-------------------------------------------------------------------------------


SYMPTOMS
========

When the drive assigned to a shared folder is viewed in File Manager or Windows
Explorer, only the root directory is shown. This was originally reported on the
120-day evaluation version of SNA Server 3.0, but may occur on the retail
version as well.

The Browse feature of the Shared Folders Gateway properties page will
successfully display all of the folders.

CAUSE
=====

Snanls.dll was not installed unless the SNA Server Print Service was also
installed. Snanls.dll does EBCDIC to ASCII translation. Here is the sample
failing trace showing a folder name query to be "aoooooooo.ooo" ('.' is
incorrectly translated a 'K' in SNA Server trace):

Here is an example of the successful case showing the query for the folder name
being "/????????.???". In this case Snanls.dll was copied to the
<Snaroot>\System directory:

NOTE: The Browse button in the Shared Folders Property page will retrieve the
folder names because the EBCDIC to ASCII translation is done internally in that
particular component. It does not rely on Snanls.dll.

RESOLUTION
==========

To work around the problem, install the Print Server feature.

The final resolution has two parts:

- Setup was modified to always install Snanls.dll.

  -and-

- Shared folders gateway now reports an error if the call to SNANLS fails.

STATUS
======

Microsoft has confirmed this to be a problem in SNA Server version 3.0. This
problem was corrected in the latest Microsoft SNA Server 3.0 U.S. Service Pack.
