An event may be logged after you restart Windows Server 2008: "Event ID: 5 Message: The Virtual Storage Filter Driver is disabled through the registry. It is inactive for all disk drives"

Symptoms

After you restart Windows Server 2008, the following event may be logged in the System log:

Log Name: System
Source: storflt
Event ID: 5
Level: Warning
Task Category: None
Message: The Virtual Storage Filter Driver is disabled through the registry. It is inactive for all disk drives.

Cause

This event is logged when one of the following scenarios is true:
  • The virtual storage filter driver cannot attach to the virtual storage device. The virtual storage filter driver is included in Windows Server 2008. This driver optimizes the performance of disk I/O if Windows Server 2008 is running on a Microsoft Hyper-V Server.
  • Windows Server 2008 is installed as the host operating system or as the guest operating system before the most recent version of Hyper-V Server is installed.

Resolution

If Windows Server 2008 is not running on a Hyper-V Server, this issue will not affect the performance of the operating system. Therefore, you can safely ignore this event.
