Lesson 20 – OTHER WINDOWS 2000 SERVER SERVICES

DHCP server DNS RAS and RRAS Internet Information Server Cluster services Windows terminal services OVERVIEW

Dynamic Host Control Protocol (DHCP): Keeps track of TCP/IP addresses. Parcels TCP/IP addresses to computers/devices that request them. Resolves address conflicts. Dynamically re-assigns addresses. DHCP Server

Requires a “scope’”. Requires other associated TCP/ IP settings that are addresses for DNS/ WINS server. Should be used for client computers.

DNS Domain Name System (DNS): Allows easily remembered names to be mapped to TCP/ IP addresses and ports. Is included in the Windows 2000 server. Is required for Active Directory to function. Can be managed with DNS Management Console plug-in.

DNS DNS Microsoft Management Console (MMC) plug-in

DNS Set up by establishing a root namespace/ creating subdomains. Manages a portion of the domain namespace. Helps to store DNS names/ communicate changes to DNS servers.

DNS Multiple DNS servers manage separate portions of DNS namespace. Updates between zones are called “zone transfers”. DNS supports full/incremental zone transfers.

DNS Considerations: Establish redundancy for DNS servers. Each zone should have at least one primary and secondary DNS server.

RAS and RRAS Remote Access Service (RAS): Provides a way to set up dial-in support to the Network. Provides access to the Network’s resources.

RAS and RRAS Routing and Remote Access Service (RRAS): Is a remote access technology with routing capabilities. Enables connections to the Network over a public Network via VPN.

RAS and RRAS Virtual Private Network (VPN): Sets up a secure “tunnel” between a client and the RRAS server, for encrypted packets to pass. Helps a client computer set up a secure connection to the RRAS server over the Internet.

RAS and RRAS Enabling RAS and RRAS:

RAS and RRAS

Use the Routing and Remote Access MMC plug-in to administer remote access

RAS and RRAS Features: Set times and days when remote access is operational/ specific users or groups can use remote access. Limit access to RRAS server/ to specific services on the Network.

RAS and RRAS Use callback feature, where a remote client dials into the Network and logs in. Set access policies based on remote client computer name or TCP/ IP address.

INTERNET INFORMATION SERVER (IIS) Includes web, FTP, SMTP, and NNTP services. Is administered through the Internet Services Manager program.

INTERNET INFORMATION SERVER (IIS) IIS Manager provides a single place to administer Internet services.

INTERNET INFORMATION SERVER (IIS) Provides comprehensive web-hosting software. Multiple web sites can be defined. Each site requires a directory to store the site’s files, security settings, and performance parameters.

INTERNET INFORMATION SERVER (IIS) Services: IIS FTP (File Transfer Protocol) enables user to set up an FTP site. NNTP (Network News Transfer Protocol) server enables user to set up a Usenet-style site. SMTP (Simple Mail Transfer Protocol) server allows SMTP connections between the system running IIS and remote SMTP mail systems.

Cluster Services Enables user to combine two or more servers into a cluster. Network load balancing clusters enable user to share TCP/IP-based services. Server clusters provide fail-over support if a server fails.

Cluster Services Considerations: Setup, care, and feeding of clusters is complicated. Cluster deployment requires a careful study of Microsoft’s documentation.

WINDOWS TERMINAL SERVICES Enables the user to set up a Windows 2000 server like a mainframe. Uses the TCP/IP connection to connect client computer to terminal server. Can create virtual Windows machine.

Windows Terminal Services Considerations: Inadequate resources. Low-bandwidth connections. Applications/ tasks.

Inadequate resources A remote computer can take advantage of the Terminal Server’s resources. So can programs requiring many processors/ direct access to large disk arrays.

Low-bandwidth connections A remote computer can have transfer display and input information. Applications requiring high-bandwidth connections run faster on the Terminal Server than a remote node connection.

Applications/ tasks Terminal services allow a remote computer to run applications and tasks that cannot be fully performed by another computer.
