Anybody that thinks SP2's Windows Firewall is such a large improvement had better make sure that they know all the facts. If you believe you need a firewall you will still not want to rely upon SP2's built in Firewall. All of the hype behind Service Pack 2's Firewall may lead most people to believe that Windows Firewall is all they need to stay safe. All of the marketing buzz gives people a false sense of security. While this IS a large step in the right direction it still is nowhere near where it should be. Anybody currently using or planning on using SP2 had better read through this carefully to find out WHY it's not anywhere near as secure as the marketing team will try to make you think.
