SYMPTOMS
The Exchange Server message transfer agent (MTA) may generate
Event ID 9301 when receiving an incoming connection from a multihomed
server.
CAUSE
By default, the MTA allows the transport to make the selection of the virtual server IP address for an outgoing connection. The transport uses all of the available virtual server IP addresses. The Exchange Server MTA that is being contacted can only have one IP address or one server name defined on the Stack property page for each X.400 Connector object. Any incoming connections from an X.400 MTA with an IP address or server name that is not configured on the Stack property page for any locally installed connectors causes an Event ID 9301, and the connection will not work.
The Event ID 9301 occurs in the event log of the receiving server approximately half of the times that a connection is attempted from a multihomed server where two virtual server IP addresses are available.
