Installed JBoss 7.1.1 Final from .zip archive. Added a management user. Started standalone.bat. localhost:8080 shows the splash page. Clicking on the Admin Console link hangs with the "Loading..." icon spinning.

Modified standalone.xml to allow remote access (management and public) and opened up Windows firewall to the java.exe program that is running JBoss. I can access the splash page and admin console remotely.
