An application that establishes a RAS connection on a Windows Embedded CE 6.0 R3-based device may crash after an access violation occurs in the Ndsil.dll component

Consider the following scenario:

• You run an application that establishes a Remote Access Service (RAS) connection on a Windows Embedded CE 6.0 R3-based device.
• The application calls the RasHangUp function immediately after it calls the RasDial function.

In this scenario, an access violation exception may occur in the Ndsil.dll component, and then the application crashes.

This problem occurs because the Network Driver Interface Specification (NDIS) code in the RasHangUp function drops all pending requests before the Layer Two Tunneling Protocol (L2TP) handler in the RasDial function finishes the OID_TAPI_MAKE_CALL pending request. Then, the access violation exception occurs.
