XP Pro Firewall Greyed Out

If you find that your XP Professional Firewall settings are greyed out, open up regedit and go to:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ WindowsFirewall
You may see entries for Domain and Standar, inside these is a Dword "EnableFirewall", double click on it and change the value to 1, reboot the computer and the Firewall should be back up and running.
