Remote Access Service
) allows a client computer
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
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:
Windows for Workgroups (Win3.11)
WinNT 3.51 and up
Serial Line Internet Protocol (SLIP) for dial-out
Point-to-Point Protocol (PPP) for dial-in only TCP/IP clients.
RAS supports the following network interfaces:
Remote Procedure Calls (RPC)
Win32 and LAN Manager APIs.
RAS supports the following protocols:
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.
