Ward Ralston – It has been a little over a year since we released Windows Server 2003 SP2. When we release a Service Pack at Microsoft, we want to make sure that IT professionals and system administrators have ample time to assess the service pack and choose when to deploy it.
As with other service packs, we offered support for Windows Server 2003 SP2 within the Windows Service Pack Blocker Toolkit. This allowed administrators to block the automatic deployment of Windows Server 2003 SP2 for a period of one year.
Now that time has expired, organizations should be aware that over the next month, support for Windows Server 2003 SP2 within the blocker tool will be phased out Windows Server 2003 SP2 will then be automatically offered, downloaded and/or installed (depending on user or administrator settings) through standard mechanisms including Windows Update and Automatic Update.
