By default, Windows Small Business Server 2003 Client Setup deploys Windows XP Service Pack 1 to all client computers running Windows XP Professional. This update changes Client Setup so that it deploys Windows XP Service Pack 2 instead. Client Setup deploys Service Pack 2 only if the language setting of the operating system on the client computer matches the language setting of the operating system on the server.
