If I understand correctly, you are trying to remove or uninstall the Windows Firewall. Windows Firewall is an embedded feature of XP and as far as I know cannot not be removed/uninstalled. I am not familiar with Norton's firewall but it may just be that during installation it disabled the Windows Firewall as it is a bad idea to run more than one firewall at a time.
Hope this is helpful.
I have XP home and cannot turn my firewall on or off. The check boxes are grayed out and it says " For your protection some settings are controlled by Group Policy"
I believe Norton Internet Security did this. I used their removal tool to rid myself of this beast to no avail.
I understand "Group Policy" is a feature of XP Pro but I have the home version.
This has affected my home network as I cannot share folders and get the "access denied see your administrator" warning box.
Please advise as this is driving me absolutely nuts.
