!ndiskd.interfaces

  • Article

The !ndiskd.interfaces extension displays information about a network interface. If you run this extension with no parameters, !ndiskd will display a list of all network interfaces.

For more information about network interfaces, see NDIS Network Interfaces.

!ndiskd.interfaces -handle <x> [-luid <x>]

Parameters

-handle
Optional handle of a network interface.

-luid
NetLuid (Net Locally Unique Identifier) of a network interface.

DLL

Ndiskd.dll

Examples

Run the !ndiskd.interfaces extension with no parameters to see a list of all network interfaces on the system. In this example, look for the Intel(R) 82579LM Gigabit Network Connection interface. Its handle is ffffdf80139f8a20.

    ffffdf80139aaa20 - Microsoft ISATAP Adapter #2
    ffffdf80139fba20 - Teredo Tunneling Pseudo-Interface

By clicking on the handle for an interface or by entering the !ndiskd.interfaces -handle command, you can see the details about that interface, including its Identifier information and its current state. In this example, you can see that the Intel(R) 82579LM Gigabit Network Connection is an Ethernet connection (its ifAlias) and is in a MediaConnectUnknown state for its connection (as it has been reserved for use by the Windows kernel debugger).
