This translates to 2880 client downloads in a 24-hour period.While this is the theoretical number of clients that can be supported in a 24-hour period if only one client is in contact with the server at any given time and there is no time gap between servicing one client and the next, a couple of factors contribute to reducing this number in reality.The guidance provided below for each option is based on the same server load assumption, so it should take approximately the same length of time to deploy Windows XP SP2 irrespective of the option implemented.
If the running version of WUA is too old or if WUA isn't running at all, install the most recent version of WUA (or at least a current version of WUA).
Introduction Key benefits of using SUS to deploy Windows XP SP2 Situation overview Factors to consider when using SUS to deploy Windows XP SP2 Overall recommendations Summary Windows XP Service Pack 2 (SP2) contains major security improvements designed to provide better protection against hackers, viruses, and worms.
But even if you know the version of WUA is out of date, you can't use the WUA API to force a self-update.
Additionally, if Windows Update on the computer is in such a state that automatic self-updates are failing, you can't use the WUA API to recover from that state.
You can use this installation package to install the latest released versions of WUA or the latest released versions of the file.
Here we explain how you can programmatically determine whether the version of WUA that is running on the computer meets your needs, that is, whether the version is the latest or at least current enough.Windows Update Agent (WUA) automatically updates itself when it is connected to a Windows Server Update Services (WSUS) server or to Windows Update.You can also use a signed installation package that is available from Microsoft to manually update WUA.You can call the IWindows Update Agent Info:: Get Info method to get current version info about WUA, but you can't determine if that version is the latest.If you receive a WU_E_SELFUPDATE_REQUIRED error message when you use the WUA API to perform a scan, download, or install, this error tells you that the version of WUA is out of date.As a best-practice approach to implementing a managed rollout of Windows XP SP2, customers are encouraged to use a corporate update management solution such as Systems Management Server (SMS) 2003 or Software Update Services (SUS).
