SYMPTOMS

When you mount a virtual hard disk (VHD) file, Windows Server 2008 Hyper-V systems restart unexpectedly, and you receive the following Stop error code:

0x1000007E

For example, you use Windows Server 2008 Virtual Machine Manager (VMM) to convert a physical drive to a virtual drive. If you use VMM to mount the captured image, the Windows Server 2008 system may experience this problem.

CAUSE

When a VHD file is corrupted, the Volsnap.sys driver may handle it incorrectly. This causes the Volsnap.sys driver to access freed memory and triggers the 0x1000007E Stop error code.
