Dial-up networking clients

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

Dial-up networking clients

A dial-up client that connects to a server running Routing and Remote Access can be any PPP client. The client must have installed a modem, an analog telephone line or other WAN connection, and remote access software.

You can automate the connection process for clients by using a simple batch file and the rasdial command. You can also schedule automatic backups to or from remote computers by using dial-up networking and Task Scheduler.

Windows-based PPP clients

Windows-based PPP clients that use TCP/IP can access a server running Routing and Remote Access. Windows-based PPP clients cannot use the AppleTalk protocol. The remote access server automatically negotiates authentication with PPP clients.

Remote access support for Windows-based PPP dial-up networking clients is outlined in the following table.

Dial-up networking client	Supported remote access PPP features	Unsupported remote access PPP features
Microsoft® Windows Server 2003 family, Windows XP, Windows 2000	Multilink, Bandwidth Allocation Protocol (BAP), Microsoft Challenge Handshake Authentication Protocol (MS-CHAP), Challenge Handshake Authentication Protocol (CHAP), Shiva Password Authentication Protocol (SPAP), Password Authentication Protocol (PAP), Microsoft Challenge Handshake Authentication Protocol version 2 (MS-CHAP v2), and Extensible Authentication Protocol (EAP)
Windows NT® version 4.0	Multilink, MS-CHAP, CHAP, SPAP, PAP, and MS-CHAP v2 (with Windows NT 4.0 Service Pack 4 and later)	BAP and EAP
Windows NT version 3.5x	MS-CHAP, CHAP, SPAP, and PAP	Multilink, BAP, MS-CHAP v2, and EAP
Windows Millennium Edition, Windows 98	Multilink, MS-CHAP, CHAP, SPAP, PAP, and MS-CHAP v2 (with the Windows 98 Service Pack 1 and later)	BAP and EAP
Windows 95	MS-CHAP, CHAP, SPAP, and PAP (with the Windows Dial-Up Networking 1.3 Performance & Security Upgrade for Windows 95 and later)	MS-CHAP v2, Multilink, BAP, and EAP

Note

• Windows 95 with the Windows Dial-Up Networking 1.3 Performance & Security Upgrade for Windows 95 supports MS-CHAP v2 over virtual private network (VPN) connections but not over dial-up connections. For more information about virtual private networks and networking upgrades, see the Microsoft Web site.

Other PPP clients

Other PPP client software that uses TCP/IP or AppleTalk can access a server running Routing and Remote Access. The remote access server automatically negotiates authentication with PPP clients. No special configuration of the server running Routing and Remote Access is required for other PPP clients except to ensure that both the remote access server and the other PPP client are configured for the same LAN and authentication protocols.

For more information, see the documentation provided with your PPP client.
