If the General tab or the On (recommended) option is unavailable, the system may have a policy against running the firewall.

In addition, the system may already be running a third-party firewall (Zone Alarm or Norton Internet Security, for example). Contact the system administrator for help in determining whether a firewall is already running on the system.
