There is a timing issue with FSDepends.sys and with VHDMP.sys. This timing issue occurs when certain backup programs are installed on computers that are running Windows Server 2008. By default, the FSDepends.sys start value in the registry is set to Manual. When any third-party backup software loads its tape device driver, the software can sometimes result in FSDepends.sys and VHDMP.sys not initializing correctly.

To work around these problems, FSDepends.sys should be set to a start value of Boot (0x0).

 
Make sure that you back up the registry before you change it.
Make sure that you know how to restore the registry if a problem occurs.
For more information about how to back up, restore, and change the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 How to back up and restore the registry in Windows
 
To work around these problems, follow these steps:
1)    Start Registry Editor.
2)    Visit the following registry key: “HKLM\SYSTEM\CurrentControlSet\Services\FsDepends”
3)    Under the “FsDepends” key, change REG_DWORD value “Start” from “3” to “0”
4)    Restart the computer

As soon as the computer is restarted, FSDepends.sys starts immediately and the timing issue no longer occurs.

Microsoft is aware of the issue and is currently investigating a resolution.

Or, you can try one of the following two workarounds. Neither of these methods is recommended. However, they work to correct the problems if editing the registry is not possible or desired.

- Turn off any attached tape device and restart the server. As soon as the server is started, turn on the tape device.

- Disable the device driver named TPFilter.sys
