Full Answer
What happens if remote access NDIS Tapi driver fails to start?
If Remote Access NDIS TAPI Driver fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the NdisTapi service has failed to start due to the error.
Does Microsoft Windows support Remote NDIS over USB?
Currently Microsoft Windows provides support for Remote NDIS over USB. The following figure shows the replacement of the device manufacturer's NDIS miniport with the combination of a Remote NDIS miniport driver and a USB transport driver.
What is the single device driver structure for Remote NDIS?
This structure allows a single device driver to be used for any Remote NDIS device for which there is a bus-specific transport layer. In addition, only one bus transport layer is required for all network devices on a specific bus. This section includes the following additional topics:
How does ndistapi work with kmddsp?
NDISTAPI (Ndistapi.sys) receives TAPI requests from KMDDSP and then calls NdisOidRequest to route the corresponding TAPI OIDs to NDIS WAN miniport drivers. For more information about NDISTAPI, see NDISTAPI Overview.
How to use ndistapi.sys file?
1. Run the Command Prompt as an administrator. 2. Copy the command below, paste it into the command window and press ENTER: sc config NdisTapi start= demand. 3. Close the command window and restart the computer. The NdisTapi service is using the ndistapi.sys file that is located in the %WinDir%System32DRIVERS folder.
What is a NDIS TAPI driver?
Remote Access NDIS TAPI Driver is a kernel device driver. In Windows 10 it is starting only if the user, an application or another service starts it. If Remote Access NDIS TAPI Driver fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the NdisTapi service has failed to start due to the error.
Default Behavior
The Remote Access NDIS TAPI Driver service is a kernel driver. If the Remote Access NDIS TAPI Driver fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the NdisTapi service has failed to start.

What is the NDIS miniport driver?
Microsoft provides an NDIS miniport driver, Rndismp.sys, which implements the Remote NDIS message set and communicates with generic bus transport drivers, which in turn communicate with the appropriate bus driver. This NDIS miniport driver is implemented and maintained by Microsoft and is distributed as part of Windows.
What is remote NDIS?
Remote NDIS (RNDIS) eliminates the need for hardware vendors to write an NDIS miniport device driver for a network device attached to the USB bus. Remote NDIS accomplishes this by defining a bus-independent message set and a description of how this message set operates over the USB bus. Because this Remote NDIS interface is standardized, one set of host drivers can support any number of networking devices attached to the USB bus. This significantly reduces the development burden on device manufacturers, improves the overall stability of the system because no new drivers are required, and improves the end-user experience because there are no drivers to install to support a new USB bus-connected network device. Currently Microsoft Windows provides support for Remote NDIS over USB.
Default Behavior
The Remote Access NDIS TAPI Driver service is a kernel mode driver. If Remote Access NDIS TAPI Driver fails to start, the error is logged. Windows 8 startup proceeds, but a message box is displayed informing you that the NdisTapi service has failed to start.

What is a WAN miniport driver?
A WAN miniport driver provides the interface between NDISWAN and WAN NICs.
What is ndistapi.sys?
NDISTAPI (Ndistapi.sys) receives TAPI requests from KMDDSP and then calls NdisOidRequest to route the corresponding TAPI OIDs to NDIS WAN miniport drivers. For more information about NDISTAPI, see NDISTAPI Overview.
What is NDPTSP?
NDPTSP (Ndptsp.tsp) is a service provider DLL that runs in the context of the TAPI service process. NDPTSP provides a TSPI interface that the TAPI service presents to TAPI-aware applications so that NDPROXY can communicate with user-mode applications.
What is the service provider for NDIS WAN miniport drivers?
The service provider for NDIS WAN miniport drivers is KMDDSP. The service provider for CoNDIS WAN miniport drivers (and MCMs) is NDPTSP.
What is a CoNDIS WAN developer?
CoNDIS WAN developers can also provide WAN client protocol drivers, a miniport call manager (MCM), or a separate call manager.
What is a tsp kmddsp?
KMDDSP (Kmddsp.tsp) is a service provider DLL that runs in the context of the TAPI service process . KMDDSP provides a TSPI interface that the TAPI service presents to TAPI-aware applications so that NDISTAPI can communicate with user-mode applications.
What is a RAS system?
The RAS system component provides transports such as PPP Authentication (PAP, CHAP) and network configuration protocol drivers (IPCP, IPXCP, NBFCP, LCP, and so on). A WAN miniport driver (or MCM) implements only PPP media-specific framing.
