Presence of anti-virus software not displayed on computers running Windows XP Service Pack 2 in a domain

If a workstation running Windows XP Service Pack 2 (SP2) is in a domain, the Windows Security Center settings do not give as much information and control to the user as they do in a workgroup:

• The Windows Security Center 'shield' icon is not displayed in the system tray
• The status of Windows Firewall, Automatic Updates and anti-virus software is not displayed
• Settings cannot be adjusted for either Automatic Updates or anti-virus software
• No Windows Security Center status alerts for anti-virus software are present.

This is because, in a domain, all such configuration and notification is performed centrally.
