SYMPTOMS
When you try to start a Microsoft Windows Server 2003-based computer that has the Volume Shadow Copy Service (VSS) enabled, the Windows Server 2003-based computer may not start.
CAUSE
This problem may occur if VSS is enabled, and the computer has many volumes. For example, this problem may occur if the computer has more than 150 volumes. In this scenario, a deadlock may occur in the Volsnap.sys driver.
