Troubleshoot MES middleware configuration issues

Access to message queuing system message is denied

If the message Access to Message Queuing system message is denied appears in the Configuration Messages box, the current Windows user does not have the required permissions to access the MSMQ MESAsyncQueue. The appropriate permissions—all permissions except Special permissions—can be assigned on the Security tab of the MESAsyncQueue Properties dialog box, accessed in the Control Panel Computer Management applet. See the example below for the user mesadmin.

Please remember to restart your middleware service to utilize new connection strings

If the message Please remember to restart your middleware service to utilize new connection strings appears in the Configuration Messages box, the middleware failed to restart. You will have to start the middleware manually for the database connection setting changes to take effect. See Start, stop, or restart the MES Middleware Host service.

Database connection fails

If any of the database connections fail, correct the settings that caused the failure and click the Configure button again. Once the connections are successful, the MES middleware service is started (or restarted) so that it is using the most recent settings. The success or failure of the restore database connection does not affect the starting of the MES middleware service.
