!ndiskd.mopen

  • Article

The !ndiskd.mopen extension displays information about bindings between miniports and protocols. If you run this extension with no parameters, !ndiskd will display a list of all open bindings between NDIS miniport drivers and protocol drivers.

!ndiskd.mopen [-handle <x>] [-ref]

Parameters

-handle
Optional handle of an NDIS open binding.

-ref
Shows refcounts of open bindings.

DLL

Ndiskd.dll

Examples

Enter the !ndiskd.mopen command to get a list of all open bindings. In this example, look for the binding between the Microsoft ISATAP Adapter #2 miniport and the TCPIP6TUNNEL protocol. Its handle is ffff8083e56b8110.

3: kd> !ndiskd.mopen
Open ffff8083e56b8110
  Miniport: ffff8083e02ce1a0 - Microsoft ISATAP Adapter #2
  Protocol: ffff8083e1a95c00 - TCPIP6TUNNEL

Open ffff8083e11902c0

Now you can either click on the handle or use the handle to enter the !ndiskd.mopen -handle command, which enables you to see more details about that open binding such as its Datapath state and Receive path information.
