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

- Microsoft SNA Server, versions 4.0, 4.0 SP1, 4.0 SP2, 4.0 SP3, 4.0 SP4 
-------------------------------------------------------------------------------

SYMPTOMS
========

On a Microsoft Windows 2000-based system, you may experience errors when you
attempt to open files that reside on a file share that was created by the
Microsoft SNA Server Shared Folders Gateway.

For example, if you use Notepad to access a text (.txt) file by using the
Universal Naming Convention (UNC) as follows

  \\<server name\share name\path\file name>.txt

you may receive the following error message:

  "Cannot open the \\<server name\share name>\test.txt file. Make sure a
  disk is in the drive you specified."

CAUSE
=====

In certain situations, Windows 2000 generates a FileInternalInformation request
when programs access files, and this request is then sent to the file server.

The Shared Folders Gateway in Microsoft SNA Server does not support the
FileInternalInformation information request type and returns an Invalid
Parameter response to the client system.

RESOLUTION
==========

A supported fix is now available from Microsoft, but it is only intended to
correct the problem that is described in this article. Only apply it to systems
that are experiencing this specific problem. This fix may receive additional
testing. Therefore, if you are not severely affected by this problem, Microsoft
recommends that you wait for the next Microsoft SNA Server version 4.0 service
pack that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services
to obtain the fix. For a complete list of Microsoft Product Support Services
