Add an anonymous logon user to MESAsyncQueue

To allow MES application objects to log messages in the Microsoft Message Queue (MSMQ) while in Without Response mode, an Anonymous Logon user with the Send Message privilege must be added to the MESAsyncQueue on the MES middleware node. Otherwise, the messages will not be logged.

Beginning with MES version 5.3, the Anonymous User login is automatically added to the MESAsyncQueue with the Send Message privilege when the DB/MW Communication component is configured using the post-install Configurator. However, if the Anonymous User login is removed from the MESAsyncQueue, you can use the following procedure to add it again.

The messages are secured end-to-end and live in the queue for a maximum of seven days. After seven days the messages are routed to the transactional dead-letter queue and the message data is lost. If the client node keeps sending the messages and is unavailable for more than one day, the messages will not be processed and the data will be lost. If the node becomes available within one day, the queued messages will be processed.
