Event ID 9301 can be a useful indicator of certain problems with X.400 Connectors. It is normally logged in the application event log by the Microsoft Exchange Server Message Transfer Agent (MTA), and can be especially useful for diagnosing bad Stack entries or problems with name lookups. However, this event ID is not be logged by certain builds of the MTA.


Some MTA builds between 2354-2620 do not log Event ID 9301. Build 2621 and later do log this event ID.

"The message transfer gateway that uses the network address xxxxxxxx and the transport stack /o=EXORG/ou=EXSITE/cn=Configuration/cn=Servers/cn=EXSERVER/cn=TCP (EXSERVER) could not be found. Check the configuration of the mail gateway. [BASE IL TCP/IP DRVR 8 218] (10)"
