Remote Access Service (RAS) allows a client computer to communicate over a dial-up connection. Unlike remote control, remote access treats the connection as a low-speed LAN connection. RAS dials the connection and negotiates the protocol with the server, after which RAS routes packets or NetBIOS calls through the host.

Remote Access Service is capable of the following:

  • Performs both the dial-out and dial-in hosting service.

  • Supports Windows NT interprocess communications.

  • Supports TDI-compliant protocols.

  • Operates over any dial-up public network/POTS medium.

  • Supports software transmission compression.

    RAS supports the following Operating Systems and connections:

  • LAN Manager

  • Windows for Workgroups (Win3.11)

  • WinNT 3.51 and up

  • Win9x

  • Serial Line Internet Protocol (SLIP) for dial-out only

  • Point-to-Point Protocol (PPP) for dial-in only TCP/IP clients.

    RAS supports the following network interfaces:

  • Windows Sockets

  • NetBIOS

  • Mailslots

  • Remote Procedure Calls (RPC)

  • Win32 and LAN Manager APIs.

    RAS supports the following protocols:

  • SLIP

  • PPP

  • TCP/IP

  • NetBEUI

  • IPX.

    RAS supports the following Wide Area Network (WAN) connections:

  • Public Switched Telephone Network (PSTN)

  • Integrated Services Digital Network (ISDN)

  • X.25 leased-line Frame Relay.

    RAS is limited to only one connection for WinNT Workstation. WinNT Server supports up to 256 connections. If you set RAS to auto-answer, it will lock the COM port and the modem. You will not be able to use the port for other services, like terminal emulaters or FAX.

    Another use of the RAS acronym in the context of computer systems is: Reliability, Availability, and Serviceability.

    If someone claims that their computer system has a 99.9% availability, that's typically an attempt to quantify the net effect of their system's RAS features. Typical RAS features include things like RAID, clustering, hotpluggable components, and so on.
