XFOR: DS_E_NO_SUCH_OBJECT Error During DirRep over IMC (190711)

SYMPTOMS

When you try to perform directory replication between two sites over the Internet Mail Service (Internet Mail Connector in version 4.0), the following error message may appear:

 Event ID 2245
 Source:  MSExchangeMTA
 Category:  Directory Access

 Directory Operation failed with problem DS_E_NO_SUCH_OBJECT. Attribute.
 Directory Name [String];
 \o=Organization\ou=Organizational_Unit\cn=Configuration\cn=Servers
 \cn=Server_Name\cn=Microsoft DSA.  [RD server DISP; Router 11  114] [8]

CAUSE

There may be two possible causes for this problem:

The value of the following registry key:
```
      HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services
      \MSExchangeMTA\Parameters\X500 DN
 
						
```
does not match the corresponding Exchange directory entry. In this case, the message transfer agent (MTA) service does not start. For more information, please see Knowledge Base article 155027, "XCON: Unable to Start Microsoft Exchange MTA; Errors 1067 & 2140."

-OR-
If a site uses an MX wildcard record, the MX wildcard record directs all messages to that site. This can mean that the Internet Mail Service tries to send messages to its own IP address. For more information, please see Knowledge Base article 150969, "XFOR: All Messages Sent Over IMC Result in NDRs."

WORKAROUND

To work around this problem, do the following:

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).

A.

Start Registry Editor (Regedt32.exe).

Under the HKEY_LOCAL_MACHINE subtree, go to the following subkey:

      System\CurrentControlSet\Services\MSExchangeMTA\Parameters\X500 DN

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 displayed in Microsoft Exchange Administrator program.

To see whether these objects match the value of the registry key, do the following:
1. Click each of these objects in the left pane of the Microsoft Exchange Server Administrator program.
2. On the File menu, click Properties. The Directory Name of each of these objects should exactly match the corresponding attribute in the registry setting described above.

B.
If you are experiencing this problem with the Internet Mail Service or IMC, you can add a registry value to prevent it. The registry key is:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
   \Services\MSExchangeIMC\Parameters

From the Registry Editor menu, click Edit, and then click the Add Value option.

   Value Name: DisableResolverSearchList
   Data Type: REG_DWORD
   Value: 1 (or any non-zero value)

This entry is case-sensitive and should be typed exactly as shown above. You must restart the Internet Mail Service for the registry key to take effect.

If the problem cannot be addressed by the information in either 155027 or Q150969, you must remove the wildcard record from the DNS server.
