ID: Q155027


The information in this article applies to:
  • Microsoft Exchange Server, versions 4.0, 5.0, 5.5

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SYMPTOMS

If you start the Exchange Server message transfer agent (MTA), it may not start, and one of the following error messages may be displayed:

Could not start the Microsoft Exchange Message Transfer Agent service on \\<servername>
Error 1067: The process terminated unexpectedly.
Could not start the Microsoft Exchange Message Transfer Agent service on\\<servername>
Error: 2140: An internal Windows NT error has occurred.
If you use the Windows NT Event Viewer to view the application event log, the following events are logged:
Event ID: 137, Source: MSExchangeMTA.
A fatal directory error occurred. Change to the maximum logging level for more details. [MTA MAIN BASE 1 15] (16)
After you change the logging to Maximum (open the properties of the MTA object, and in the Diagnostics Logging page, click Directory Access and Field Engineering), the MTA logs one of the following error messages in the Event Viewer:
Event Id: 2245, Type: Warning, Category: Directory Access Directory operation (ds_read) failed with problem DS_E_NO_SUCH_OBJECT. Attribute . Directory Name (string): /O=<organization> /OU=<site>/CN=CONFIGURATION/CN=SERVERS/CN=<server name>/CN=MICROSOFT MTA. [RD Server MAIN BASE 1 114] (8)
Event 2241: Directory operation (ds_search) failed with problem DS_E_NO_SUCH_OBJECT. Attribute: . Root Directory Name: / o=<organization>/ou=<site>/cn=Configuration/cn=Connections. [RD Server MAIN BASE 1 116] (12)


CAUSE

The value of the following registry key in the HKEY_LOCAL_MACHINE subtree does not match the corresponding directory entry:

System\CurrentControlSet\Services\MSExchangeMTA\Parameters\X500 DN
The wrong Organization or Site name was used when Exchange Server was reinstalled on the server.


RESOLUTION

Check the value of the registry key and edit it, if necessary, so that it matches the corresponding directory entry, or reinstall Exchange Server using the correct Organization and Site names.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

  1. Start Registry Editor (Regedt32.exe).


  2. Under the HKEY_LOCAL_MACHINE subtree, go to the following subkey:


  3. System\CurrentControlSet\Services\MSExchangeMTA\Parameters\X500 DN
  4. Check the value for this key. The Organization [o=], Site [ou=], and Server Directory names [cn=] must exactly match the properties of the Organization, Site, and Server objects as they are displayed in the Exchange Server Administrator program.

    To see whether these objects match the value of the registry key:


    1. In the left pane of the Exchange Server Administrator program, click to expand the Organization object, click to expand the Site object, and then click to expand the Server object.


    2. On the File menu, click Properties. The Directory Name of each of these objects must exactly match the corresponding attributes in the registry setting described in step 3.



MORE INFORMATION

When the Exchange Server MTA starts, it checks the Distinguished Name (DN) of the MTA object in the registry and verifies that it is exactly the same as the one that is stored in the Exchange Server directory.
