Issues starting SSBExternal Activator (service-specific error code 21)


  • I installed SQL Server External Activator 2012 on my local machine. I have windows 7 Professional and SQL Server 2012 Express installed. After the installation I go to services to start it and receive the following error:

    "Windows could not start the Service Broker External Activator on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 21."

    I went to the servers system log this is the error I found:

    "The Service broker External Activator service terminated with e service-specific error. The device is not ready..."

    An idea what could be causing this? I get this error in these two environments:

    Windows Server 2008 RS

    SQL Server 2012 


    Windows 7 Professional

    SQL Server 2012 Express
