| RAS (Remote Access Services)
RAS is capable of using the following connection protocols:
SLIP - Has less overhead than PPP, but cannot automatically assign an IP address, and only uses TCP/IP.
PPP - Can automatically assign IP addresses, supports encryption and other protocols besides TCP/IP.
RAS - Used by Windows 3.x and Windows NT 3.x clients.
RAS supports call back security to either the calling number or to a specified, non-changing number.
RAS for NT 4.0 supports multilink (the use of more than one modem to achieve higher transmission speeds). Multilink cannot be used with callback security unless there are two (or more) ISDN modems configured on the same phone number.
RAS uses NetBEUI as the default network protocol, but can also use TCP/IP and IPX/SPX. TCP/IP will need to be used if you are using programs that utilize the Windows Sockets (Winsock) interface over the RAS services.
RAS will default to the first network protocol on each side of the connection. Thus, if NetBEUI is the first protocol that is in common, Winsock applications (such as a web browser) will not be available to the client.
To speed up NetBIOS resolution on RAS clients, put an LMHOSTS file on each client locally.
RAS encryption settings
Allow any authentication including clear text - This will allow RAS to use a number of password authentication protocols including the Password Authentication Protocol (PAP) which uses a plain-text password authentication. This option is useful if you have a number of different types of RAS clients, or to support third-party RAS clients.
Require encrypted authentication - This option will support any authentication used by RAS except PAP.
Require Microsoft encrypted authentication -This option will only make use of Microsoft's CHAP (Challenge Handshake Authentication Protocol). All Microsoft operating systems use MS-CHAP by default.
Require data encryption - This option will enable the encryption of all data sent to and from the RAS server.
RAS will write to a log file which can be used for troubleshooting RAS services. In order to enable RAS to write to the log, you have to enable it in the Registry.
