As more and more organizations migrate their physical servers to virtual machines, the types of problems associated with physical servers are becoming increasingly more common in enterprise environments. For example, in the old days (which in reality were only a few years ago) system administrators sometimes had to wrestle with physical servers crashing with the notorious Blue Screen Of Death (BSOD). Also known as a stop screen, this blue screen provides only minimal information about what might have caused the problem but it can suffice in some circumstances to help you identify the cause of the crash. If your server (either physical or virtual) is running Windows Server 2008 or Windows Server 2008 R2, a good source of information on how to troubleshoot BSODs is Chapter 32 Troubleshooting Stop Messages of the Windows 7 Resource Kit from Microsoft Press, and most of the information in this chapter is still relevant for Windows Server 2012 and Windows Server 2012 R2 as well.

If you succeed in mounting the .vmdk file, copy the data to a new virtual disk as soon as possible.
