  1. Lesson 20 – OTHER WINDOWS 2000 SERVER SERVICES

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

  3. DHCP Server 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.

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

  5. 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.

  6. DNS DNS Microsoft Management Console (MMC) plug-in

  7. 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.

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

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

  10. 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.

  11. 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.

  12. 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.

  13. RAS and RRAS Enabling RAS and RRAS:

  14. RAS and RRAS

  15. RAS and RRAS

  16. RAS and RRAS Use the Routing and Remote Access MMC plug-in to administer remote access

  17. 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.

  18. 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.

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

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

  21. 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.

  22. 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.

  23. 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.

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

  25. 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.

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

  27. 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.

  28. 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.

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

  30. SUMMARY • Dynamic Host Control Protocol (DHCP) • Domain Name System (DNS) RAS and RRAS: • Virtual Private Network • Steps to enable RAS and RRAS • Features

  31. Summary Internet Information Server : • Services Cluster services : • Considerations

  32. Summary Windows terminal services: • Inadequate resources. • Low-bandwidth connections. • Applications/ tasks, which cannot be fully optimized by another computer.
