Win7 Enterprise SP1 - can't restart docker daemon on boot2docker machine - docker toolbox 1.9.1

After installation of Docker Toolbox v1.9.1 on windows:

Boot2Docker version 1.9.1, build master : cef800b - Fri Nov 20 19:33:59 UTC 2015
Docker version 1.9.1, build a34a1d5
docker@default:~$

And now I an trying to restart docker daemon:

docker@default:~$ sudo /etc/init.d/docker restart
Need TLS certs for default,127.0.0.1,10.0.2.15,192.168.99.101
-------------------

but the docker daemon has actually stopped and I can't start it anymore:

docker@default:~$ sudo /etc/init.d/docker status
Docker daemon is not running
docker@default:~$ sudo /etc/init.d/docker start
Need TLS certs for default,127.0.0.1,10.0.2.15,192.168.99.101
-------------------
docker@default:~$ sudo /etc/init.d/docker status
Docker daemon is not running
docker@default:~$ docker ps
Cannot connect to the Docker daemon. Is the docker daemon running on this host?

What is really strange is that using "docker.exe" straight from Windows everything looks good:

$ docker ps -a
CONTAINER ID        IMAGE                                COMMAND                  CREATED             STATUS                      PORTS                   NAMES

How is that possible that when I ssh into the "default" docker VM I can;t see the "docker daemon running but from windows I can list, start and run containers ?

maybe docker-machine ssh tail /var/log/docker.log will tell you more

yes, it sounds very unusual - though you could create this issue by setting the docker daemon to only listening to the tcp socket, and not /var/run/docker.sock
