XFOR: Imcadmin.dll Should Not be Renamed or Deleted

• Microsoft Exchange Server, version 4.0

SUMMARY

Imcadmin.dll is required for an administrator to change the properties of the Microsoft Exchange Internet Mail Connector (IMC) using the Microsoft Exchange Administrator program. This DLL is not protected in any way and can be renamed or deleted even when the property page of the IMC is open.

MORE INFORMATION

If this file is renamed or deleted, the next time that an administrator attempts to open the property page of the IMC, they will receive an error message stating:

   Extension 'SMTP' could not be loaded.

   An error occurred during file replication. Unable to find the extension
   .DLL file with the correct version number. To view details of the error,
   see the application event log in the Windows NT Event Viewer on the
   Microsoft Exchange Server computer.

   The file version of "\add-ins\SMTP\<platform>\imcadmin.dll" installed on
   the local server is not current. Unable to locate a correct version on
   any server in the site."

RESOLUTION

This behavior is by product design. Do not delete or rename this file.

If the file was deleted, it can be copied from the Setup\<platform>\Add- ins\Smtp\<platform> directory on the Microsoft Exchange Server CD.

If this file exists on another Microsoft Exchange Server in the same Site, it will be dynamically replicated the next time the IMC property page is opened.
