Introduction to Windows Server 2003 Chapter 08

  1. 1. Hands-On Microsoft Windows Server 2003 Chapter 8 Managing Windows Server 2003 Network Services
  2. 2. Objectives • • • • Implement Microsoft DHCP Implement Microsoft DNS Implement Microsoft WINS Install and configure Internet Information Services • Configure a Telnet server 2
  3. 3. Microsoft DHCP • Protocol in TCP/IP suite • Used with DHCP Services to detect the presence of a new network client and assign an IP address to that client • The DHCP server has an assigned range of addresses – A contiguous range of addresses is called a scope – Multiple scopes are allowed in a single DHCP server to reflect subnet structure or network divisions – Each address is assigned for a specific period of time 3
  4. 4. Microsoft DHCP, cont. • A single DHCP server can support up to 1000 scopes and 10,000 DHCP clients – A Microsoft recommendation, not a limit • Option to automatically register forward and reverse lookup zone records with a DNS server • DHCP server automatically updates the DNS server when it assigns an IP address • Install DCHP using the Add and Remove Programs tool – Networking service in Windows components 4
  5. 5. 5
  6. 6. Configuring a DHCP Server • Set up one or more scopes of contiguous address ranges – Provide DNS servers’ IP addresses when configuring each scope • Activate each scope • Authorize the DHCP server – Used as security precaution to ensure careful management of IP addresses • Configure DHCP server and its clients to automatically update DNS records – Recommended, but not required 6
  7. 7. 7
  8. 8. Configuring Automatic DNS Registration • Verify that the DHCP server is set up to automatically register the IP addresses it leases • Verify that the DHCP server is configured for the types of clients on your network – For servers with only Windows 2000, XP, or Server 2003 clients, dynamically update records only if requested by clients – Otherwise, always dynamically update DNS records – For servers with Windows 95, 98, or NT clients, dynamically update records for clients that do not request updates 8
  9. 9. 9
  10. 10. 10
  11. 11. Microsoft DNS • Provides DNS namespace • Resolves computer names to IP addresses and IP addresses to computer names • Most compatible DNS server with Active Directory – Offers DNS replication through Active Directory • DNS servers should have static IP addresses • Installation similar to other Windows components, such as DHCP – Install before or while installing Active Directory 11
  12. 12. 12
  13. 13. DNS Zones • Partition containing resource records in a lookup table • Forward lookup zone – Holds host name records that link computer names to IP addresses – Automatically created for a DC in a domain – Host address (A) resource record is for IPv4 – Host address (AAAA) resource record is for IPv6 – One server can have several forward lookup zones 13
  14. 14. DNS Zones (cont.) • Reverse lookup zone – – – – Holds the pointer (PTR) record Contains links from IP addresses to host names Not automatically configured when DNS is installed Can be used for monitoring a network with IP address information – Create a reverse lookup zone before DNS forward lookup zone records are created • When a forward lookup zone is created, an associated reverse lookup zone PTR record can be automatically created 14
  15. 15. 15
  16. 16. 16
  17. 17. 17
  18. 18. Using the DNS Dynamic Update Protocol • Enables information in a DNS server to be automatically updated in coordination with DHCP • Saves administrators a great deal of time • Verify that DNS is configured to use the DNS dynamic update protocol – Make the updates Secure, so only authorized clients can perform an update • DHCP servers must also be configured to perform DNS registration 18
  19. 19. 19
  20. 20. DNS Replication • Primary DNS server – Designated as the authoritative server for a zone – All changes to the zone must be made on this DNS server • Secondary DNS servers – Contains a copy of the primary DNS server’s zone database – Is not used for modifications – Serves as a backup in case of failure – Performs load balancing – Reduces congestion 20
  21. 21. DNS Replication (cont.) • One DNS server can be authoritative for multiple domains • One DNS server can be a secondary server for more than one primary server • One DNS server can be a primary server for one zone and a secondary server for another zone • If using Active Directory with two or more DCs, set up DNS services on at least two DCs to enable multimaster replication – Provides uninterrupted DNS services for the network 21
  22. 22. Troubleshooting DNS • Make sure that the DNS server and DNS Client services are both started and set to start automatically on the DNS server • Use the Computer Management tool to check the settings – Status information – Startup type box should be set to Automatic 22
  23. 23. Microsoft WINS • Automatically registers network clients that use NetBIOS • Builds a database that other network clients can query in order to locate a computer • Installation is similar to DHCP and DNS • Typically use default configuration settings – Can configure for replication with other WINS servers in a domain • Troubleshoot by making sure WINS is started, or by stopping and restarting to reinitialize the service 23
  24. 24. Microsoft Internet Information Services • Allows Windows Server 2003 to behave as a Web server and offer a Web site • Included with the Windows Server 2003 installation CD-ROM • Includes the Internet Server Application Programming Interface (ISAPI) – Group of DLL files that are application and filters – Application enables linking of other programs and speeds program execution – Filters are used to automatically trigger programs 24
  25. 25. Microsoft Internet Information Services (cont.) • IIS contains World Wide Web services • An IIS server can function as an SMTP, NNTP, and FTP server • Windows Server 2003 provides: – Privileged-mode architecture – Fault tolerance capabilities – Database access using IIS Open Database Connectivity (ODBC) drivers • IIS is compatible with security techniques such as MPPE, IPSec, and SSL encryption 25
  26. 26. 26
  27. 27. Installing IIS • Windows Server 2003 installed on the host computer • TCP/IP installed on the IIS host • Access to an ISP – IP address, subnet mask, and default gateway IP address • Sufficient disk space for IIS and Web site files • Disk storage formatted for NTFS for performance and security • Name resolution method 27
  28. 28. Virtual Directory • URL formatted address that provides an Internet location for an actual physical folder on a Web server – URL format consists of the server name, an alias for the virtual directory, and the file name • Used to access and publish Web documents • Create a virtual directory using the Virtual Directory Creation Wizard in the IIS Manager • Configure security and other options using the properties tab 28
  29. 29. 29
  30. 30. 30
  31. 31. 31
  32. 32. Managing and Configuring an IIS Web Server • Application pools – Groups similar Web applications for management • SMTP virtual server – Manages Internet e-mail • NNTP virtual server – Manages newsgroup services • Web service extensions – For compatibility with FrontPage – Enables the use of other extensions, such as Active Server pages and Internet printing 32
  33. 33. Managing and Configuring an IIS Web Server (cont.) • Web sites – Manages multiple Web sites from one administrative Web server – One default Web site is automatically set up – Has several configuration parameters, including directory security with authentication access options • The default is anonymous access 33
  34. 34. 34
  35. 35. 35
  36. 36. 36
  37. 37. Windows Media Services • Provides streaming media services – Streaming mode allows audio and video to begin playing as soon as received • Separate from the IIS component • Enables a Web server to serve voice and video multimedia applications • Install using Add/Remove Windows Components after IIS is installed 37
  38. 38. Telnet Server • Protocol in TCP/IP suite that enables a client to act as a terminal to access a server • Particularly useful for non-Windows clients • Requires the following: – Telnet Server running on Windows Server 2003 – Microsoft Telnet Client or another version of Telnet on the client computer – Server and client must be configured for TCP/IP – User must have a user account and supply the account name and password when logging in 38
  39. 39. Telnet Server • Uses NTLM authentication to protect server access • Windows Server 2003 Telnet Server Service can be started in two ways: – Through the Computer Management tool – From the Command Prompt window: • Start telnet by typing “telnet servername” • View a command prompt window on the server • Enter “telnet /?” to view telnet command information 39
  40. 40. 40
  41. 41. Summary • DHCP is a work-saving protocol because it enables IP addresses to be leased dynamically • Configuring DHCP involves configuring scopes, which are ranges of IP addresses from which addresses are leased to clients • Plan to configure DHCP to dynamically update DNS • Part of configuring DNS involves forward and reverse lookup zones 41
  42. 42. Summary • Configure Dynamic DNS to enable automated IP address registration in coordination with a DHCP server • Plan to set up two or more DNS servers on most networks and to integrate DNS with Active Directory for DNS replication and load balancing • If your network uses NetBIOS naming, install WINS • To implement a Web server, install Internet Information Services 42
  43. 43. Summary • Create IIS virtual directories to enable multiple users to publish on a Web site • Plan to configure each Web site to control client timeout, server bandwidth, number of connections, and authentication • Install Windows Media Services to enable a Windows 2003 Server, including one configured with IIS, to provide streaming multimedia • If you have users, such as UNIX computers, that need to connect using Telnet, configure Windows 2003 as a Telnet Server 43
