I have a headless windows server 2008 R2 running, and obviously I forgot to enable remote administration. Every attempt to connect via remote desktop, even with the administrator user, is currently rejected because remote desktop isn't licenced. Which is correct, because I don't need it on that mashine, just should be able to configure the system from time to time.
So I'm a bit lazy: I don't want to shut down the system, carry it over to some place with monitor and keyboard, change the configuration, shut it down again and carry it back.
Is there a way to remotely connect to the machine and activate the remote administration via network, so that I can connect again?
