The Microsoft Cluster Shared Volume namespace filter driver (CsvNSFlt.sys) startup type on node {0} is not set to the default and recommended value of DEMAND_START (0x3).  This may have been changed by another application or by an administrator during the troubleshooting of a problem.  This setting affects whether the driver is automatically started and at what point in the system boot process that the driver starts.  To change the setting back to the recommended value, open "Registry Editor" and go to the following key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CsvNSFlt.  Change the "Start" value to 0x3
