SYMPTOMS

You may be in a situation where you need to remove Exchange Server and reinstall it. After you reinstall Exchange Server, you try to reinstall the Exchange Notes Connector. After the Setup program copies all the files and tries to create the Connectivity Controller service, the installation does not work, and a message appears indicating that the service is already installed.

CAUSE

The Exchange Server 5.5 Setup program is not aware of the Connectivity Controller and its connector services. When you click the Remove All option in the Exchange Server 5.5 Setup program, the Connectivity Controller and connector services are not removed.

RESOLUTION

To resolve this problem, you must manually remove the Connectivity Controller and Connector services. This involves deleting the corresponding registry entries and support files.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
  1. Start the Windows NT Registry Editor.
  2. At the following subkey, delete the entire MSExchangeCoCo key:

    \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeCoCo

    At the following subkey, delete the entire LME-NOTES key:

    \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LME-NOTES

  3. Move or delete the Exchsrvr\Connect\Exchconn folder.
  4. Shut down all Exchange Server services and reboot the server.
  5. Install the Connector for Lotus Notes.
