XCON: DRAS Fails with Event 9322

• Microsoft Exchange Server, versions 5.0, 5.5

SYMPTOMS

When you attempt to connect two Microsoft Exchange Server 5.5 computers using the Dynamic RAS (DRAS) connector over TCP/IP, and the servers are in two different, untrusted domains, the Exchange Server computer that dials may log a 9318 and a 289 message transfer agent (MTA) event in the application log. The Exchange Server computer that is being dialed into will log a 9322 event with a Windows NT/MTA error of 5:

9322: MSExchangeMTA
An interface error has occurred. An MtaBindBack over RPC has failed.
Locality Table (LTAB) index: %1, NT/MTA error code:5.
Comms error %3, Bind error %4,Remote Server Name %5, Protocol String %6 [%7 %8 %9 %10]

CAUSE

A Windows NT error code of 5 signifies that there is a security problem between the two servers.

WORKAROUND

1. Create a new Windows NT user account called RASCON. Repeat this process on each of the untrusted domains.



2. Give the new RASCON accounts the exact same password.



3. Add the RASCON account to the Domain Admins group.



4. Verify that the RASCON account has permission to log onto the Exchange Server computer. This is done using the Windows NT User Manager.



5. Within the Microsoft Exchange Administrator program, give the new RASCON account Service Account Admin permission at the Organization, Site, and Configuration levels of the Exchange Server computer.



6. Adjust the RAS Override tab of the DRAS connector to use these new accounts on both Exchange Server computers.



7. Retest mail flow over the DRAS Connector.
