By selecting this check box, you are making sure that information
passing through your connection will be encrypted. Unlike data compression, encryption protects
the contents of the data during transmission. Even though this option provides relatively weak
encryption, you might want to use it when you are transmitting critical data. Note that your performance
will suffer slightly with this option because the encryption is processed in software.

Require Encrypted Password
By selecting the Require Encrypted Password check box, you are
precluding the use of cleartext authentication. Microsoft supports several encrypted password
options, including Shiva Password Authentication Protocol (SPAP), Data Encryption Standard
(DES), Challenge Handshake Authentication Protocol (CHAP), and MS-CHAP. MS-CHAP is
based on Rivest-Shamir-Adleman (RSA) MD4 (Message Digest type 4). On Windows NT, this is
enhanced to MD5 with Service Pack 3 or greater, and is standard in newer versions of Windows.
Remember when choosing your password that passwords are generally
case sensitive.

Enable Software Compression
Software-based compression is different from the modem-based
compression features that were presented in Chapter 23, “Asynchronous Connections.” By selecting
this option, you can improve throughput by enabling compression, but this depends on the
type of data and equipment you use. By compressing with software, you are substituting a repetitious
series of characters to reduce the amount of bandwidth required. When decompressing, the
compressed data stream is translated back into an uncompressed form.

Log On to Network
If you are connecting to an NT domain, you use this option to establish
a network connection and to attempt to log into the domain. Leave this option unselected to
improve performance on networks where this service is not required.

Advanced Options
Microsoft considers optional functions to be advanced options. These options include settings
to control compression and authentication protocols.
Under Advanced Options, five choices can be made by the user or administrator.
