Establishing a Dial-Up Connection to the Internet
The following functions are used to handle modem connections.
WinINet dial-up functions do not support double-dial connections, SmartCard authentication, or connections that require registry-based certification.
Starting on Windows Vista and Windows Server 2008, the WinINet dial-up functions use the RAS functions to establish a dial-up connection. WinINet supports the functionality documented in the RasDialDlg function.
WinINet does not support server implementations. In addition, it should not be used from a service. For server implementations or services use Microsoft Windows HTTP Services (WinHTTP).
