The !ndiskd.protocol command displays information about an NDIS protocol driver. If you run this extension with no parameters, !ndiskd will display a list of NDIS protocol drivers that are active on the system.

!ndiskd.protocol [-handle <x>] [-findname <any>] 


Handle of an NDIS protocol.

Filters protocols by name prefix.




Enter the !ndiskd.protocol command to see a list of all NDIS protocols, their handles, and open bindings to miniports (if any). In the following example, look for the TCPIP6TUNNEL protocol's handle, ffff8083e1a95c00.

3: kd> !ndiskd.protocol
ffff8083e0114730 - NDISUIO
  ffff8083e55f3010 - Microsoft Kernel Debug Network Adapter

ffff8083e3e90c10 - MSLLDP
  ffff8083e3926010 - Microsoft Kernel Debug Network Adapter

ffff8083e3e98c10 - WANARPV6

ffff8083e3e97010 - WANARP

ffff8083e3e8f6b0 - RSPNDR
  ffff8083e11902c0 - Microsoft Kernel Debug Network Adapter

ffff8083e3e90800 - LLTDIO
  ffff8083e15537d0 - Microsoft Kernel Debug Network Adapter

ffff8083e1a9ac10 - RDMANDK

ffff8083e1a95c00 - TCPIP6TUNNEL
  ffff8083e56b8110 - Microsoft ISATAP Adapter #2

ffff8083e19bec10 - TCPIPTUNNEL

ffff8083e19bfc10 - TCPIP6
  ffff8083e504c770 - Microsoft Kernel Debug Network Adapter

ffff8083e11cec10 - TCPIP
  ffff8083e0c565a0 - Microsoft Kernel Debug Network Adapter

With the protocol's handle, now you can enter either click the handle or enter the !ndiskd.protocol -handle command to see information for that protocol, such as the handles for the miniports that are bound to it.
