• FIREWALL OPTIONS GRAYED OUT:
Deploying Windows Firewall Settings With Group Policyhttp://www.microsoft.com/technet/prodtechn...t/wfsp2wgp.mspx
When you use Group Policy to configure Windows Firewall, by default local administrators will be unable to change some elements of its configuration locally, using the Windows Firewall component in Control Panel. Some tabs and options in the Windows Firewall dialog box will be grayed out and unavailable, even for local administrators.

If the options on the General, Exceptions, and Advanced tabs are grayed out, it means you are not logged on to the computer with a user account that has administrative permissions. A user with administrative permissions must log on to the computer to change the firewall options, or to change your user account to an administrative account.
