Updating policy not set for windows xp in group sophos
The first variant of Conficker, discovered in early November 2008, propagated through the Internet by exploiting a vulnerability in a network service (MS08-067) on Windows 2000, Windows XP, Windows Vista, Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2 Beta.
The procedure to update your Group Policy object with the new Windows Firewall settings will replace the file that is stored for the Group Policy object being modified with the version that is provided with Windows XP SP2, which includes the new Windows Firewall settings.
The best way to manage Windows Firewall settings in an organization network is to use Active Directory and the new Windows Firewall settings in Computer Configuration Group Policy.
This method requires the use of Active Directory with either Windows 2000 or Windows Server 2003 domain controllers.
The network was subsequently quarantined, forcing aircraft at several airbases to be grounded because their flight plans could not be downloaded.
The United Kingdom Ministry of Defence reported that some of its major systems and desktops were infected.
