PRODUCT :Microsoft Visual Basic for Windows
PROD/VER:WINDOWS:4.0
OPER/SYS:WINDOWS
KEYWORDS:vb432 VB4WIN

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

 - Microsoft Visual Basic Standard and Enterprise Editions, 32-bit only,
   for Windows, version 4.0
---------------------------------------------------------------------

SYMPTOMS
========

When upgrading Microsoft Exchange Server from 4.0 or 5.0 to 5.5, you may
need to re-register some DLLs in the Visual Basic references menu.

CAUSE
=====

When Visual Basic is installed on an Exchange Server computer, and the
Exchange version is upgraded to 5.5, some DLLs become unregistered due to
version changes and will require re-registering in Visual Basic.

RESOLUTION
==========

There is no workaround.

STATUS
======

Microsoft has confirmed this to be a problem. We are researching this and
will post new information here in the Microsoft Knowledge Base as it
becomes available.
