Hi, Please check the following link. Oracle 11g release 2 - Microsoft Windows Installation Guide http://www.oracle.com/pls/db112/portal.portal_db?selected=11&frame=#microsoft_windows_installation_guides By the way, this is an Oracle issue instead of a Windows system issue, as we mainly focus on the General question about Windows Server 2008 system and here is not the best support resource for Oracle, it is recommend you to contact Oracle to get further support so that you can get the most qualified pool of respondents.
