I recently decided to try the Windows Live OneCare application. I believe it is a sort of combo antivirus/firewall app. Now, I notice that my Windows Firewall is not turned on. I'm thinking that the OneCare turned it off. When I try to turn it on, the box is grayed out. It also said something about some setting being controlled through Group Policy. I don't know what this means. Other than installing the OneCare, I haven't done anything with "Group Policy" and I don't even know how to do this. I'm thinking that the OneCare app has done this. It has been acting as a firewall, since it has told me that it has allowed such and such program access in the last few days.
