Thank you for your post.
What version of Java is installed on the host server and/or the remote machine if you are attempting to launch remotely? Are you using localhost, 127.0.0.1 or the Server IP address in the web browser?
I have the same setup (FMSA 12 on WinServer 2008 R2) and I CAN use my admin console GUI, but any attempt to access (restart or stop) the Admin Server from the CLI returns the 10007 error as mentioned by Florian above. I am using Java 1.7.0_25-b17.
