Why each option
SPAP (Shiva Password Authentication Protocol) is the authentication protocol used by Shiva clients when dialing in to computers running Windows 2000 Server via remote access.
IWA (Integrated Windows Authentication) is used for browser-to-web-server authentication over HTTP/HTTPS in intranet environments, not for dial-in remote access connections.
Digest authentication is an HTTP challenge-response scheme for web application authentication and is not used as a PPP-layer dial-in authentication protocol.
MPA is not a recognized standard authentication protocol for Windows 2000 dial-in remote access services.
SPAP is a reversible encryption authentication protocol supported by Windows 2000 Remote Access Service specifically to allow Shiva LAN Rover clients to authenticate when dialing in; Windows 2000 RAS supports SPAP for interoperability with these third-party clients.
