MS-Windows XP service pack 2 comes with in build firewall. If Microsoft Windows Firewall is blocking a port that is used by a service or by a program, you can configure the Windows Firewall to create an exception. Windows Firewall may be blocking a program or a service if Programs do not respond to a client's request or you do not get data from server.

Yes, hello,
I am trying to download Norton on the computer I am using right now. I have Norton already on another computer, but need it on this one as well. I have gone through all the steps as shown on this website, but I still can not download Norton. As soon as I click the “DOWNLOAD” button it says it could not connect to FTP etc. etc. I have checked and re-checked and ports 20 and 21 are both on the exception list. Is there anything else I could try?
