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.
