Microsoft TCP/IP Core Technology and Third-Party Add-Ons

Microsoft TCP/IP provides all the elements necessary to implement these protocols for networking. Microsoft TCP/IP includes the following:

Core TCP/IP protocols, including the Transmission Control Protocol (TCP), Internet Protocol (IP), User Datagram Protocol (UDP), Address Resolution Protocol (ARP), and Internet Control Message Protocol (ICMP). This suite of Internet protocols provides a set of standards for how computers communicate and how networks are interconnected. Support is also provided for PPP and Serial-Line IP (SLIP), which are protocols used for dial-up access to TCP/IP networks, including the Internet.
Support for application interfaces, including Windows Sockets 1.1 for network programming, remote procedure call (RPC) for communicating between systems, NetBIOS for establishing logical names and sessions on the network, and network dynamic data exchange (Network DDE) for sharing information embedded in documents across the network.
Basic TCP/IP connectivity utilities, including finger, ftp, lpr, rcp, rexec, rsh, telnet, and tftp. These utilities allow Windows NT users to interact with and use resources on non-Microsoft hosts, such as UNIX workstations.
TCP/IP diagnostic tools, including arp, hostname, ipconfig, lpq, nbtstat, netstat, ping, route, and tracert. These utilities can be used to detect and resolve TCP/IP networking problems.
Services and related administrative tools, including the FTP Server service for transferring files between remote computers, Windows Internet Name Service (WINS) for dynamically registering and querying computer names on an internetwork, Dynamic Host Configuration Protocol (DHCP) service for automatically configuring TCP/IP on Windows NT computers, and TCP/IP printing for accessing printers connected to a UNIX computer or connected directly to the network via TCP/IP.
Simple Network Management Protocol (SNMP) agent. This component allows a Windows NT computer to be administered remotely using management tools such as SunNet Manager or HP Open View. SNMP can also be used to monitor DHCP servers and to monitor and configure WINS servers.
The client software for simple network protocols, including Character Generator, Daytime, Discard, Echo, and Quote of the Day. These protocols allow a Windows NT computer to respond to requests from other systems that support these protocols. When these protocols are installed, a sample QUOTES files is also installed in the \systemroot\SYSTEM32\DRIVERS\ETC directory.
Path MTU Discovery, which provides the ability to determine the datagram size for all routers between Windows NT computers and any other systems on the WAN. Microsoft TCP/IP also supports the Internet Gateway Multicast Protocol (IGMP), which is used by new workgroup software products.

The following figure shows the elements of Microsoft TCP/IP alongside the variety of additional applications and connectivity utilities provided by Microsoft and other third-party vendors.

TCP/IP standards are defined in Requests for Comments (RFCs), which are published by the Internet Engineering Task Force (IETF) and other working groups. The relevant RFCs supported in this version of Microsoft TCP/IP (and for Microsoft Remote Access Service) are described in the following table.

In this version of Windows NT, Microsoft TCP/IP does not include a complete suite of TCP/IP connectivity utilities, Network File System (NFS) support, or some TCP/IP server services (daemons) such as routed and telnetd. Many such applications and utilities that are available in the public domain or from third-party vendors are compatible with Microsoft TCP/IP.

Tip For Windows for Workgroups computers and MS-DOS–based computers on a Microsoft network, you can install the new version of Microsoft TCP/IP—32 for Windows for Workgroups and the Microsoft Network Client version 2.0 for MS-DOS from the Windows NT Server 3.5 compact disc. This software includes the DHCP and WINS clients and other elements of the new Microsoft TCP/IP software. For information about installing these clients, see Chapter 9, "Network Client Administrator," in the Windows NT Server Installation Guide.
