Se você estiver tentando definir uma política de grupo para o Internet Explorer 10 usando o Server 2003, precisará baixar e instalar modelos administrativos .
Administrative Template files are used to populate user interface settings in the Group Policy Object Editor, enabling administrators to manage registry-based policy settings. However, for Windows Server 2003, the Administrative Template files need to be manually imported, as Internet Explorer 10 installation is not supported on that Operating System. An IT Admin may want to manage Group Policy settings on a mixed environment of Internet Explorer 10 and earlier versions from a Windows Server 2003 machine.
