Event ID: 9316
The Windows NT error 1783 in Event 9316 equates to "Bad Stub Data." This
problem occurs when the number of messages in the outbound DRAS connector's
queue exceeds the DRAS connector's configured threshold. By default, the
Threshold value is set to 50. When the queue exceeds this threshold, an
additional association is generated. However, the sending MTA passes an
invalid context handle to the receiving MTA, which terminates the
connection because the handle is invalid.
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 5.5. This problem has been corrected in the latest U.S. Service
Pack for Microsoft Exchange Server version 5.5.
Event ID: 9322
The calling Exchange Server MTA issues a RPC bind command that contains a
TCP port number to be used in the reply, the bindback RPC command. When
replying, the called MTA does not use this port number, and as the firewall
is configured to let go through only this port number, the reply is never
received by the calling MTA. The communication is not established and as a
result no mail can be sent or received.
To resolve this problem, obtain the latest service pack for Exchange Server
