disabled nwam - how to undo?

I installed Solaris 11 Express on my machine and connected to it remotely using putty. I then run the

svcadm disable /network/physical:nwam

command to stop the NWAM service.

Now I cannot connect to the Solaris machine remotely anymore, but I have physical access to it as well.

How do I undo disabling that service?

svcadm enable /network/physical:nwam

produces an Pattern /network/physical:nwarm doesn't match any instance error.

Thank you for helping me,
Dusan

nwarm != nwam
