Microsoft Internet Security and Acceleration Server 2000


backup domain controller (BDC)
A server that receives a copy of the security policy and master database for a Windows 2000 domain. The master database contains centralized security data for all domain-assigned users and is updated when changes in security are made. See also primary domain controller (PDC), member server.
The data transfer capacity of a digital communications system.
bandwidth control
The practice of setting the maximum network capacity that a service is allowed to use. You can deliberately limit a server's workload by not allowing it to receive requests at full capacity, saving resources for other programs, such as e-mail.
basic authentication
A method of authentication that encodes the user name and password. Basic authentication is called "clear text" because the encoding (base-64) can be decoded by anyone with a freely available decoding utility. Note that encoding is not the same as encryption. See also Windows 2000 challenge/response authentication.
See backup domain controller (BDC).
BIND service
See Domain Name System (DNS).
A process that establishes the initial communication channel between the protocol driver and the network adapter driver.
A numeric value intended for a bit-by-bit value comparison with other numeric values, typically to flag options in parameters or return values. Usually this comparison is done with bitwise logical operators, such as And and Or in Visual Basic, and ampersand (&) and pipe (|) in C++.
bits-per-second (bps)
The basic rate of data transmission.
block filter
An IP packet filter that completely blocks access to specific ports or from specific IPs.
See bootstrap protocol (BOOTP).
bootstrap protocol (BOOTP)
A Transmission Control Protocol/Internet Protocol (TCP/IP) protocol that allows a diskless client computer to determine its own Internet Protocol (IP) address, the IP address of the server, and the name of a file to be loaded into memory and executed. DHCP provides a superset of the functions provided by BOOTP.
See bits-per-second (bps).
The delivery of data packets to all computers on a network.
A tool for navigating and accessing information on either the Internet or an intranet.
