Cause of the Error

computer Support

In your Windows 7, or Windows Server 2008 R2 PC, there is an introduction of a new NDIS Light Weight Filter (LWF) driver known as ‘WFP Lightweight Filter.’ When you install Windows from the media to a local disk, the filter gets bound to all the network adapters present in your PC. On the other hand, when you install your Windows from the media directly to an iSCSI disk, the Windows installation tries to ensure that the LWF filter is not getting bound. Additionally, the installation process ensures that LWF filter is not bounding the network adapter used for the iSCSI boot.

If the alternate iSCSI boot adapters are also available on the PC, then the LWF filter may get bound to these adapters thus resulting in the BSOD. The BSOD appears because neither the LWF filter serves as a boot start driver, nor it is compatible with the paging I/O.

What to Do Next?

To resolve the error, you can go online from a different PC, or a handheld device to search various tech support forums, troubleshooting guides, etc. If there is no other computer, or a device available, then you can visit a local computer technician to get the computer problems fixed. In case you are not able to find any local technician, then try to find a toll-free number of an online PC repair company, and connect with them to obtain the quick resolution.
