In trying to add a GPO to turn off the Windows Firewall feature on a Windows 2003 / XP SP2 environment, I get a message that the "GPO is not applied because it was filtered out". It is "empty". I have checked all of the permissions and made sure that "Authenticated Users" are there, along with their proper permissions. Does anyone know what is going on? I've created and used this GPO successfully at other client locations. However, I am now scratching my head on this one.
