Security on Windows

The WebSphere MQ Explorer uses Component Object Model (COM) technology to communicate between servers and between processes on a server.

The COM server application, AMQMSRVN, is shared between any client processes that need to use the WebSphere MQ COM Services.

Because AMQMSRVN must be shared between non-interactive and interactive logon sessions, you must launch it under a special user account. This special user account is called MUSR_MQADMIN. When you install WebSphere MQ and run the Prepare WebSphere MQ Wizard for the first time, it creates a local user account for AMQMSRVN called MUSR_MQADMIN with the required settings and permissions. The password for MUSR_MQADMIN is randomly generated when the account is created, and used to configure the logon environment for AMQMSRVN.

The password is not known outside this onetime processing and is stored by the Windows operating system in a secure part of the Registry.
