Norton's Systemworks is a collection of different utilities, one of which is a Firewall.
You will need to open up the Firewall application window, (probably from the firewall icon in the System Tray near the clock), and find the options or Tools>Options to tell it to allow Internet Explorer and Outlook express to have internet access.
I recently installed Norton Systemworks on my XP system and found that I can no longer surf the internet with Internet Explorer or receive email with Outlook Express. If I turn off the Norton protection IE and Outlook Express resume working. Why is this happening? And what can I do to correct it?
