TITLE   :XFOR: How to Re-add Extensions to Exchange for OV/VM Connector
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:exc55

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

 - Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you uninstall the Microsoft Exchange Connector for IBM OV/VM (OV/VMC) from
a site with multiple OV/VMC, then attempt to administer a remaining OV/VM
Connector using the Exchange Server Administrator program, the following error
messages may occur:

   Extension 'lsovvcp0' could not be loaded. The extension for Microsoft
   Exchange Administrator's CPU type has not been installed in the site.
   Microsoft Exchange Administrator ID no: c1031667

   Extension 'LSMSGTRK' could not be loaded. The extension for Microsoft Exchange
   Administrator's CPU type has not been installed in the site. Microsoft
   Exchange Administrator ID no: c1031667

   Extension 'LSQVIEW' could not be loaded. The extension for Microsoft Exchange
   Administrator's CPU type has not been installed in the site. Microsoft
   Exchange Administrator ID no: c1031667

Selecting Ignore on each error message opens the OV/VMC property pages, however
the Options and the Message Tracking tabs will be missing. Moreover, the Queues
tab will only show two queues, the MTS-IN and the MTS-OUT queues.

CAUSE
=====

When one OV/VMC is uninstalled from a site that inculdes several OV/VMC, the
replication process removes the Exchange Server extensions supporting the OV/VMC
from all Exchange servers in the site. Mail flow still works, but the above
error messages occur when you attempt to access the property page for the
OV/VMC.

RESOLUTION
==========

To re-add these missing components, run the following commands from the
Exchsrvr\Connect\Exchconn\Install directory of an existing OV/VM Connector
(substitute your Exchange Server Organization, Site, and Server names in the
appropriate places). These commands add these missing components and propagate
the components to the other servers in the site.

   mexiextn /org=<ORG> /site=<SITE> /server=<SERVER>
   /machine=i386 /name=LSMSGTRK
   /extdll=\\server\add-ins\lsmsgtrk\i386\lsmsgtrk.dll /display_name="Extension
   for Connectivity Message Tracking for i386"

   mexiextn /org=<ORG> /site=<SITE> /server=<SERVER>
   /machine=i386 /name=LSQVIEW /extdll=\\server\add-ins\lsqview\i386\lsqview.dll
   /display_name="Extension for Connectivity Queue Viewer for i386"

   mexiextn /org=<ORG> /site=<SITE> /server=<SERVER>
   /machine=i386 /name=LSNTSCP0
   /extdll=\\server\add-ins\lsovvcp0\i386\lsovvcp0.dll /display_name="Extension
   for OV/VM Connector for i386"

After you run each command individually, review the Lmeilog.txt file in the same
directory, and look at the last entry to see if the command was successful.
Alternatively, in the Exchange Server Administrator program, select the Add-ins
container (press F5 to refresh), and see if the component now appears. If the
display name for the component does not appear in the list, the command was
unsuccessful.
