This chapter provides a detailed discussion of Windows Server 2008 networking, including an explanation of Transmission Control Protocol/Internet Protocol (TCP/IP), versions 4 and 6, routing, network address translation (NAT), legacy protocols, and other topics related to Windows Server 2008 network configuration.
A little more than a decade ago, TCP/IP was used by a relatively small number of computers connected to the Internet. As the number of networks connected to the Internet grew explosively, and as companies expanded to include more and more networks within the enterprise, TCP/IP has come to be the protocol of choice for most organizations. The reasons are many, but they commonly include the organization's need for standardization, the capability to route, and of course, Internet connectivity.
Windows Server 2008 offers strong support for TCP/IP. TCP/IP is the primary protocol for, and the foundation of, Active Directory (AD), which is the keystone of Windows Server 2008 networks. On the client side, the TCP/IP protocol enables full support for connecting to both peer and server computers running TCP/IP, the Internet, and TCP/IP-based services such as networked printers.
