XCON: Routing and Remote Access Service Connection Does Not Work with 9301 Warning on Receiving Server (256844)

RESOLUTION

Exchange Server 5.5 Service Pack 1 and later versions of Exchange Server allow you to define an IP address to use for outbound X.400 connections over Routing and RAS. To implement this feature, perform the following steps on the originating Routing and RAS Exchange Server computer:

1. Identify the Relative Distinguished Name (RDN) of the X.400 Connector by using the Microsoft Exchange Server Administrator program in raw mode. You need this name to implement the necessary registry modifications on the server:WARNING: If you use the raw mode of the Exchange Server Administrator program (admin /r) incorrectly, serious problems may occur that may require you to reinstall Microsoft Windows NT Server, Microsoft Exchange Server, or both. Microsoft cannot guarantee that problems that result from using raw mode incorrectly can be solved. Use raw mode at your own risk.
   
   
   1. Start the Exchange Server Administrator program in raw mode by typing the following at a command prompt:

      c:\exchsrvr\bin\admin /r

   2. Double-click Site, double-click Configuration, double-click Connectors, and then select the X.400 Connector object in the right pane.
   3. On the File menu, click Raw Properties to open the raw properties of the X.400 Connector.
   4. In the Object Attribute column, click Obj-Dist-Name, and in the Attribute Value box, scroll to the right until you locate the last "cn=" value. This is the RDN that you use to create the registry key name. For example, if the X.400 Connector object is named "TCP to MTA B," the value for the Obj-Dist-Name object attribute is displayed similar to the following:

      /o=Organization/ou=Site/cn=Configuration/cn=Connection/cn=TCP to MTA B

      In this example, the RDN value is "TCP to MTA B." Select this value, and copy the value.
2. Use the RDN value ("TCP to MTA B" in this example) that you copied from the Exchange Server Administrator program in raw mode to create a registry key: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 Registry Editor (Regedt32.exe).
   2. Locate the following key in the registry:

      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeMTA\Parameters

   3. On the Edit menu, click Add Key, and then add a registry key. In the Key Name box, paste the RDN value that you copied from the Exchange Server Administrator program in raw mode, and leave the Class box blank. In this example, the Key Name is "TCP to MTA B."
   4. Select the new registry key. On the Edit menu, click Add Value, and then add the following registry value:

      Value Name: Stack IP Address Override
      Data Type: REG_SZ
      Value: The IP address of the originating server, in standard dot notation (for example, 123.123.123.123)

      This IP address is now used as the From IP address when you create a connection to the recipient server.
   5. Quit Registry Editor.
3. Stop and then restart the Exchange Server message transfer agent (MTA) service so that the changes take effect.

Note that these changes are only required for X.400 Connectors that create outbound Routing and RAS connections. This change does not affect incoming messages.
