Tomorrow June 12th we will release the Windows Server 2003 SP2 through the Automatic updates and Windows Server Update Services.
We changed the way SP2 will be installed/delivered through our systems. You will now have more control on the installation behavior of Windows Server 2003 SP2 because the Update EULA acceptance screen and the SP2 Welcome screen will now be shown as part of the Windows Server SP2 install over WU Site and Automatic Updates. WSUS admins will also be required to explicitly accept the SP2 EULA in order to enable automatic deployment.
