1. SQL SERVER cannot start and reported ‘Failed to allocate pages’. It looks like memory shortage issue. But we are quite sure that the server has enough memory. So we decided to focus on ‘Detected unsupported pre-release version of Windows 7 or Windows Server 2008 R2.‘ Because it looks abnormal. The windows OS is win2016. Why SQL SERVER found it was ‘pre-release version‘ ?
