訊息佇列無法驗證傳送到 %1 的訊息。因為佇列只接受驗證過的訊息，所以訊息已被拒絕。可能是傳送者沒有簽署訊息，或是使用自我簽署憑證來簽署訊息。如果傳送者要求，則會傳送未到達通知。最短每隔 %2 秒會記錄此事件一次。若要變更此設定，請將 \HKLM\Software\Microsoft\MSMQ\Parameters\Event2195 登錄值設定為想要的時間 (以秒為單位)。

Message Queuing could not authenticate a message sent to queue %1. The message was rejected because the queue only accepts authenticated messages. It is possible that sender did not sign the message, or signed it with a self-signed certificate. A negative arrival acknowledgement will be sent if requested by the sender. This event is logged at most once per %2 seconds. To change this setting, set \HKLM\Software\Microsoft\MSMQ\Parameters\Event2195 registry value to desired time in seconds.
