Objectives for this Chapter Diagnose and resolve issues related to Automatic Private IP Addressing (APIPA) Practice:

In This Chapter Understanding Network Infrastructures Networking with Default Components in Windows Server 2003 Extending a Windows Server 2003 Network Infrastructure

To Complete the Exercises: Physically networked two computers. Performed a Windows Server 2003 installation with default settings on both computers. The computers should be named Computer1 and Computer2. Assigned the local Administrator account on both computers a strong password of your choosing. Created a private user account, with your name, that has not been granted Administrator privileges.

Understanding Network Infrastructures A network infrastructure is a set of physical and logical components that provide the basis for connectivity, security, routing, management, access, and other integral features on a network.

Physical Infrastructure A network’s physical infrastructure is its topology—the physical design of the network—along with hardware components such as cabling, routers, switches, bridges, hubs, servers, and hosts.

Logical Infrastructure the logical infrastructure include network components such as Domain Name System (DNS), network protocols such as TCP/IP, network client software such as Client Service For NetWare, and network services such as the Quality of Service (QoS) Packet Scheduler.

Small Organization Need to Know: How to install and configure network protocols required for various network needs; How to configure manual and automatic addressing methods appropriate to network needs; How to configure name resolution methods; and How to troubleshoot network problems related to connectivity, addressing, access, security, and name resolution.

Medium And Large Networks Configuring remote access through dial-up connections and virtual private networks (VPNs); Creating, modifying, and troubleshooting routing interfaces and routing tables; Creating, supporting, and troubleshooting security based on public key cryptography; and Making maintenance decisions for heterogeneous networks that include operating systems such as Microsoft Windows, UNIX, and Novell NetWare

Analyzing Windows Server 2003 Networks Network Connections –Network connections are logical interfaces between software (such as protocols) and hardware (such as modems or network adapters).

Network Protocols –Network protocols are network languages used for computer-to- computer communication.

Note TCP/IP is actually a group of protocols referred to as a stack or suite. This protocol stack includes Address Resolution Protocol (ARP), Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Domain Name System (DNS), Hypertext Transfer Protocol (HTTP), and many others.

Network Services Network services are programs that provide features, such as quality of service, to hosts or protocols on a network.

Network Clients In Windows, Network clients are programs that allow a computer to connect to a network operating system.

Addressing Addressing is the practice of maintaining a coherent system of addresses within your network so that all computers can communicate.

Name Resolution Name resolution is the process of translating a computer name into an address, and vice versa. Windows can use two different naming systems, NetBIOS and DNS,

Network Computer Groups A workgroup is a simple grouping of resources intended to help users find such resources as printers and shared folders. By default, computers in Windows workgroups use the NetBIOS naming system to name computers and resolve those names. A domain is a collection of computers, defined by a network administrator, that share a common directory, security policies, and relationships with other domains. Security and directory information are stored in domain controllers within each domain.

Active Directory Active Directory is a distributed database and directory service that is replicated among all domain controllers on the network. The Active Directory database stores information about network objects including domains, computers, users, and other objects.

Remote Access Remote access connections must be configured for users who connect to a Windows network from a non-local site. The two basic methods for remote access include direct dial-up to a network computer and virtual private networks.

Network Address Translation Network Address Translation (NAT) is a method of allowing computers internal to your network that have been given nonpublic addresses to communicate with computers on the Internet.

Certificate Infrastructure Certificates are used for public key cryptography, which is an important security element in Windows Server 2003 networks. Certificates and public key cryptography are used in many Windows features, such as; –The Secure Sockets Layer (SSL), –The Internet Protocol –Security (IPSec) protocol (which encrypts IP communications), –Smart cards, and –The Encrypting File System (EFS, which secures files on a network).

Networking with Default Components in Server 2003 In a Windows network, a connection is a logically configured interface between a physical network and a network adapter or modem. Windows Server 2003 automatically detects and configures connections associated with network adapters installed on the local computer.

Viewing Default Components of Network Connections The network clients, services, and protocols associated with (or bound to) the connection provide connectivity through any particular connection. There are Three tabs: General Tab:

Viewing Default Components of Network Connections There is the Authentications Tab:

Viewing Default Components of Network Connections There is the Advanced Tab:

Viewing Advanced Connection Settings You can also adjust the binding order of the services used for each connection.

Provider Order tab The Provider Order tab of the Advanced Settings dialog box, displays the order in which various network providers, such as a NetWare Network, Microsoft Windows Network, or Microsoft Terminal Services, will be attempted

Default TCP/IP Settings Set to obtain an IP address Automatically

Automatic Private IP Addressing An IP address in the range of – is APIPA. APIPA is an addressing feature for simple networks that consist of a single network segment. And when no DHCP server or alternate configuration is available.

APIPA Disabling APIPA 1.Use the Registry Editor Regedit.exe to add the Registry entry IPAutoconfigurationEnabled with a value of 0 (REG_DWORD data type) in the following subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Se rvices\Tcpip\Parameters\Interfaces\interface 2.Restart the computer. Disable APIPA on multiple adapters: 1.Set the value of the IPAutoconfigurationEnabled entry to 0 (REG_DWORD data type) in the following Registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Se rvices\Tcpip\Parameters 2.Restart the computer.

Exam Tip Be sure to memorize the APIPA-related Registry keys for the exam.

Troubleshooting IPCONFIG –/ALL –/RELEASE –/RENEW –/FLUSHDNS –/REGISTERDNS –/DISPLAYDNS –/SHOWCLASSID –/SETCLASSID

Setting an Alternate Configuration This will replace APIPA when the DHCP is not available.

Default Networking and Workgroups Default in a single workgroup named WORKGROUP. Computer names are NetBIOS names, resolved using NetBT broadcasts to the local network segment.

Routing and Windows Server 2003 Network Infrastructure This will be covered later Windows Server 2003 does install the Routing And Remote Access service in a disabled state.

Extending a Windows Server 2003 Network Infrastructure Adding Components to a Connection –Installing Client Service For NetWare

Frame Types and the NWLink (IPX) Protocol When installed, you may manually configure with: –Internal Network Number –Frame Type

NWLink Choosing a frame type may be: –Ethernet –Ethernet –Ethernet II –Ethernet SNAP

Installing Windows Networking Components By using the Add Or Remove Programs tool Add /Remove Windows Components

Four Subcomponents related to the Network Infrastructure: Management And Monitoring Tools Networking Services Component Other Network File And Print Services Component Certificate Services Component

Exam Tip Be sure to know the functions of the Network File And Print Services subcomponents for the exam

Adding Active Directory to a Windows Infrastructure Adding Active Directory dramatically changes the logical infrastructure of a Windows network. Active Directory Add a Global Catalog. –A global catalog that contains information about every object in the directory And a replication service that distributes directory data across the network.
