• Windows Firewall is disabled. You cannot use the Windows Firewall tool in Control Panel to turn on Windows Firewall or to configure Windows Firewall settings on the Windows XP SP2 client computer. When you try to configure Windows Firewall settings, some options are appear dimmed, and you may receive the following message:
  For your security, some settings are controlled by Group Policy.
  You experience this symptom even if you previously clicked On (recommended) in the Windows Firewall dialog box to turn on Windows Firewall.
• You cannot use the Security Center item in Control Panel on the Windows XP SP2 client computer to manage security settings.

Note These symptoms occur if either of the following conditions is true:

• You install Windows XP SP2 on a client computer that is located in a Microsoft Windows Small Business Server (SBS) 2003-based network.
• You have joined a client computer that is running Windows XP SP2 to a Windows SBS 2003-based network

This issue occurs because Group Policy in Windows Small Business Server 2003 disables Windows Firewall for client computers that are running Windows XP Professional.

An update is available for Windows Small Business Server 2003 that configures the Group Policy settings for Windows Firewall on Windows XP SP2-based computers.

After you install the Windows Small Business Server 2003 Update for Windows XP SP2 update, you can use the security features that are included in Windows Firewall on a computer that is running Windows XP SP2. The update changes the default Group Policy setting in Windows Small Business Server 2003 to enable Windows Firewall on client computers that are running Windows XP Professional SP2. Additionally, the update opens the ports and makes it possible to use the program exceptions that Windows Firewall requires to work with the features that are included in Windows Small Business Server 2003. After you install the update, Windows Firewall is enabled on client computers that are running Windows XP Professional SP2. However, note that Internet Connection Firewall remains disabled on client computers that are running Windows XP Professional Service Pack 1 (SP1) or earlier.

The update does not include the .adm files that you must have to manage the additional Windows XP SP2 settings for Internet Explorer and Windows Update. You use the Inetres.adm file and the Wuau.adm file to manage Internet Explorer and Windows Update settings. To manage the Windows XP SP2 settings for Internet Explorer and Windows Update, install the Windows Server 2003 Administration Tools Pack on a Windows XP SP2-based computer. You can then manage the Group Policy settings from the Windows XP SP2 computer that is running the Administration Tools.
