Starting July 13, 2010 Microsoft will end “Mainstream Support” for Windows Server 2003 and enter into “Extended Support.”
What Does this Mean to You?
Microsoft will continue to provide security updates for Windows Server 2003 but will no longer provide non-security related hot-fixes, no-charge incident support, warranty claims, design changes or feature requests.
Windows Server 2003 will remain in Extended Support until July of 2015, at which time all updates for Windows Server 2003 will be discontinued.
