3.3.2.7.1 Transport Connection Time-Out
This event is triggered when the RPC transport indicates to RPC that the connection has timed out. Different RPC transports interpret this differently. Connections using NCACN_IP_TCP as the transport time-out when the Connection Time-Out Timer expires. For information on how a given RPC transport times out connections, see the documentation for the respective transport. When this event occurs on a connection, all security and presentation contexts are considered invalid. All calls that are in progress on this connection are considered failed, and an implementation-specific error is returned to the higher-layer protocol. A call is considered in progress on a connection if at least one PDU has been sent for that call and not all PDUs from the server have been received for that call.
