!ndiskd.vc

  • Artikel

The !ndiskd.vc extension displays a Connection-Oriented (CoNDIS) virtual connection (VC).

!ndiskd.vc -handle <x>

Parameters

-handle
Required. Handle of a VC pointer.

DLL

Ndiskd.dll

Remarks

For more information about CoNDIS, see Connection-Oriented NDIS.

For more information about CoNDIS virtual connections, see Virtual Connections.

Examples

CoNDIS is used in certain situations such as connecting to a VPN, so running !ndiskd.vc will not show you results unless a miniport driver on your system has created and activated a CoNDIS virtual connection. The following example shows results from a machine that is connected to a VPN network. First, run the !ndiskd.netadapter extension with no parameters to see a list of miniports and miniport drivers on the system. In the following output, look for the miniport driver for the Marvell AVASTAR Wireless-AC Network Controller network adapter. Its handle is ffffc804af2e3710.

Next, enter the !ndiskd.vc command with the miniport driver's handle to see the virtual connections opened by that miniport driver.
