256986 Description of the Microsoft Windows Registry



SYMPTOMS
When you try to manually start the Microsoft Exchange Internet Mail Connector (IMC) on a Microsoft Windows NT 4.0 computer, you may receive the following error message:

Services

Could not start the Microsoft Exchange Internet Mail Connector service on \\.

Error 2140: An internal Windows NT error occurred.

Additionally, the following event ID message may be logged in the Application event log:

Event ID: 4086

Source: MSExchangeIMC

Type: Error

Category: Initialization/Termination

Description: Unable to start the service because the configuration could not be loaded from the Microsoft Exchange directory or Windows NT Registry.



CAUSE
This issue may occur if the value of the following registry key does not match the corresponding directory entry:

HKEY_LOCAL_MACHINE\ System\CurrentControlSet\Services\MSExchangeIMC\Parameters\SiteDN

This issue may also occur if the wrong Organization or Site name was used when Exchange Server was reinstalled on the computer.



RESOLUTION
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.

To resolve this issue, edit the value of the registry key so that it matches the corresponding directory entry, or reinstall Exchange Server using the correct Organization and Site names.

To edit the registry:  Start Registry Editor (Regedt32.exe). Locate the SiteDN value under the following key in the registry:

HKEY_LOCAL_MACHINE\ System\CurrentControlSet\Services\MSExchangeIMC\Parameters\SiteDN

 Check the value for this key. Make sure that the Organization [o=] and Site [ou=] exactly match the properties of the Organization, Site, and Server objects as they are displayed in the Exchange Server Administrator program. The Server directory name [cn=] is not required. The MSExchangeIMC is not specific to the CN. To determine the names of these objects, follow these steps:  Start the Administrator program. In the left pane, expand the Organization object, expand the Site object, and then expand the Server object. On the File menu, click Properties. The directory name of each of these objects must exactly match the corresponding attributes in the registry setting that is described in step three.</li></ol> </li> Quit Registry Editor.</li></ol>
