SYMPTOMS
Consider the following scenario:
 * You are running a Windows Server 2003 R2-based computer or a Windows Server 2003 R2 Service Pack 2-based computer.
 * Many storage volumes are mounted on this computer.
 * You enable Volume Shadow Copy Service (VSS) and the File Server Resource Manager (FSRM) quota.

When you try to restart the computer in this scenario, the system startup process stops responding (hangs) when the progress bar reaches 25 percent. Therefore, you have to turn off the computer. However, after you do this, you may experience one of the following symptoms:
 * Although the computer can be successfully restarted, the VSS data and the snapshot information are missing.
 * The computer continues to stop responding during startup until you use safe mode to unmount some volumes.



CAUSE
This problem occurs because of a deadlock among the filter manager, the mount manager, VSS, and FSRM.
