Symptoms

When you access shared resources from a computer that is running Windows Server 2008 or Windows Vista, the computer crashes randomly. For example, the issue occurs when you log on to the computer or when you start an application that accesses shared resources. Additionally, the computer does not recover until you force the computer to restart.

Cause

This issue occurs because of a deadlock in the Redirected Drive Buffering SubSystem (Rdbss.sys) driver.
