Are you receiving an error code when creating or starting a queue manager on Windows?

If the IBM MQ Explorer, or the amqmdain command, fails to create or start a queue manager, indicating an authority problem, it might be because the user under which the IBM MQ Windows service is running has insufficient rights.

Ensure that the user with which the IBM MQ Windows service is configured has the rights described in User rights required for an IBM MQ Windows Service. By default this service is configured to run as the MUSR_MQADMIN user. For subsequent installations, the Prepare IBM MQ Wizard creates a user account named MUSR_MQADMINx, where x is the next available number representing a user ID that does not exist.
