Could you tell by using the troubleshooting tips at
whether the broker was running at this point?
Was the "nodedown" a result of running the rabbitmqctl script?
Were the .erlang.cookies matching at this time?

What command preceded this error, and was there any additional
information following the error?

This is not a problem. You must set the %ERLANG_HOME% variable in any

I would recommend using the "rabbitmq-service.bat remove" command to
remove the service. See the documentation:
Running "SC DELETE" may have caused problems. There are additional
registry keys that need to be removed if you want to completely remove
the service. On my workstation they are under
You must use the rabbitmq-service.bat (or the Erlang Service Manager
directly) to modify services. If these fail then you may need to remove
the registry keys manually. Needless to say, this is not standard
operating procedure and you risk even more serious problem if you make a
mistake. Take a backup first.

Clean up the registry and make sure you install and remove the service
using the rabbitmq-service.bat script. Your experience suggests that we
could add more troubleshooting tips. Please let us know if you wish to
