  • Article

The !ndiskd.filterdriver extension displays information about an NDIS filter driver. If you run this extension with no parameters, !ndiskd will display a list of all filter drivers.

!ndiskd.filterdriver -handle <x> [-filters] [-handlers]

Parameters

-handle
Optional handle of an NDIS filter driver.

-filters
Displays instances of this driver's filters.

-handlers
Displays this driver's filter handlers.

DLL

Ndiskd.dll

Examples

Run !ndiskd.filterdriver with no parameters to see a list of all filter drivers on the system. In the following example, look for the Virtual WiFi Filter Driver, whose handle is ffffbc064cc83be0.

0: kd> !ndiskd.filterdriver
    ffffbc064ccd4900 - QoS Packet Scheduler
    ffffbc064cc83be0 - Virtual WiFi Filter Driver
    ffffbc064cb91a10 - WFP vSwitch Layers LightWeight Filter
    ffffbc064cb8fd70 - WFP Native MAC Layer LightWeight Filter
    ffffbc064cb59b00 - WFP 802.3 MAC Layer LightWeight Filter

By clicking the filter driver handle from the previous example or by using it to enter the !ndiskd.filterdriver -handle command in the command window, you can get see more detailed information about that filter driver. In this case, for example, there are no filter modules for this filter driver.
