Components of dial-up networking

Dial-up networking includes the following components:

• Dial-up networking servers

  You can configure a server running Routing and Remote Access to provide dial-up networking access to an entire network or restrict access to the shared resources of the remote access server only.

• Dial-up networking clients

  Remote access clients running a member of the Windows Server 2003 family, Windows XP, Windows 2000, Windows NT running Remote Access Service (RAS) or Routing and Remote Access Service (RRAS), Windows Millennium Edition, Windows 98, Windows 95, or Mac OS can all connect to a server running Routing and Remote Access.

• LAN and remote access protocols

  Application programs use LAN protocols to transport information. Remote access protocols are used to negotiate connections and provide framing for LAN protocol data that is sent over wide area network (WAN) links. Routing and Remote Access supports LAN protocols such as TCP/IP and AppleTalk, which enable access to Internet, UNIX, Mac OS, and Novell NetWare resources. Routing and Remote Access supports remote access protocols such as PPP.

• WAN options

  Clients can dial in by using standard telephone lines and a modem or modem pool. Faster links are possible by using ISDN. You can also connect remote access clients to remote access servers by using X.25 or ATM. Direct connections are also supported through an RS-232C null modem cable, a parallel port connection, or an infrared connection.

• Security options

  The Windows Server 2003 family provides logon and domain security, support for security hosts, data encryption, Remote Authentication Dial-In User Service (RADIUS), smart cards, remote access account lockout, remote access policies, and callback for secure network access for dial-up clients.

The following illustration shows the dial-up networking components. Your actual implementation and configuration of dial-up networking may vary.
