Article: Q165534
Product(s): Microsoft SNA Server
Version(s): WINDOWS:3.0

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

- Microsoft SNA Server, version 3.0 
-------------------------------------------------------------------------------


SYMPTOMS
========

When configuring link services on SNA Server Manager, if the link service title
string is less than 11 characters, you will receive the following messages:

  Link Service Error - This link service cannot be configured using SNA Server
  manager. To configure this link service, run the External Link Service tool
  from tools menu.

CAUSE
=====

The DWORD variable containing the size of a buffer used to store a registry
value wasn't being set, and therefore the value containing the link service DLL
name could not be determined.

RESOLUTION
==========

This fix sets the buffer to the size it was before calling RegQueryValueEx.

WORKAROUND
==========

You can change the link service title to a length greater than 11 character in
the registry.

The value in the registry is:

  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services
     \SnaSdlcx\Parameters\Title

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.
