This article describes how to troubleshoot a stop error, also called a “blue screen” error, on Amazon Web Services (AWS) instances of Windows Server 2008 R2 when using 16+ cores. There is a known limitation with WinPcap on AWS 16+ vCPU Windows 2008 instances. A workaround is to use the open source variant of WinPcap called Win10Pcap. More information on this open-source variant can be found at http://www.win10pcap.org/.
