suppose that I have an windows server that serves my LAN, is there any possible way that I can download windows XP updates to my windows server and my clients will just get update from the windows server so they will not consume that much bandwidth during the update?

Hi, What you asked is WSUS. For more information, you can refer to: Windows Server Update Services http://technet.microsoft.com/en-us/wsus/default.aspx Best Regards, Vincent Hu

Hi , With WSUS you can perform your operation, WSUS gives you centralized management ofthe updates and manage the clients along with the schedule.
