Message Transfer Agent (MTA):

CAUSE
One of the causes of this error is a timing error occuring during a
connection attempt. The MTA sends a connection request at the transport
layer,
and may receive a connection confirm for the transport layer before the MTA
has prepared the connection at the session layer (CN SPDU).
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server,
version 4.0.
This problem was corrected in the latest Microsoft Exchange 4.0 Server U.S.
Service Pack. For information on obtaining the service pack, query on the

MORE INFORMATION
This timing issue was resolved by readying the session layer connection
request (CN SPDU) before sending the connection request for the transport
layer.
