It is fully routable and is often used as a basis for wide area networks WANs. Fast Infrared Protocol. Fast infrared protocol can give a computer wireless LAN access.
This protocol supports devices with a throughput of up to 4 Megabits per second Mbps. Throughput is a measure of the data transfer rate through a typically complex communications system or of the data processing rate in a computer system.
ATM Asynchronous Transfer Mode ATM is a high-speed network technology capable of transmitting data, voice, and video traffic in real time using fixed-length packets transmitted over reserved network bandwidth. ATM is a connection-based protocol and therefore must establish a connection before transmitting any data. ATM Call Manager. This level establishes the connection initiates the call and communicates with the switch hardware that is analogous to a hub in an Ethernet environment.
You can set up bridges to other network segments or partition part of the ATM network to form a smaller segment. At the least, each network adapter you install in the computer requires an IP address and a subnet mask. Assigning an IP Address. If you want to assign an IP address, perform the following procedure:.
Click on Properties. On the IP Address tab see Figure 8. If you do not have a computer on your network that can act as a DHCP server, or if you need to assign a permanent, static address to your computer, you should specify an IP address and subnet mask manually.
Important If you use a static IP address, make sure the address is accurate. If you assign an incorrect number, your computer may not be able to communicate on the network. You could also prevent another user from being able to use the network.
Obtaining an IP Address Automatically. This new Windows 98 mechanism causes the computer to assign itself an IP address in the form of Windows 98 will continue to use this address until it detects the presence of a DHCP server.
Consequently, computers enabled with Automatic Private IP Addressing can communicate only with computers that also have addresses of the form Assigning a Gateway. In order to access computers on other subnets, your Windows 98 computer must be configured for one or more gateways, a combination of hardware and software that connect two different types of networks.
Although you can have as many as eight gateways in the Installed Gateway list see Figure 8. Because gateways entered manually will supersede the ones assigned through DHCP, if you manually enter a gateway assignment, be careful not to override the DHCP-provided default gateways. When you attempt to connect to another computer running Windows 98, your computer will query the WINS server to find out the IP address of the remote computer.
Without a WINS server, you need to maintain a text database file that contains computer names-to-IP address mappings to connect to computers on remote subnets. DNS is a hierarchical naming system that uses a combination of text names separated by periods to create a unique name, such as example. The DNS server contains a database that converts the name assigned to your computer into a number.
The number enables the computer to connect to the network. If you enable DNS, you can use your host name a name to identify your computer on a local network plus a domain name or suffix to create an Internet address. This utility enables you to see not only your IP address but also your subnet mask and other information that could be critical to your setup. Click Start , then Run and type winipcfg. Releasing an IP address before the lease has expired makes the address available for assignment to other computers.
Troubleshooting a Connection Using Ping. The ping command verifies a connection to a remote host by sending four by default ICMP echo packets to the host and listening for echo reply packets. The ping command waits for up to one second for each packet sent and prints the number of packets transmitted and received. To test a connection, you can use the ping command with the following options:.
If a ping to a remote host fails, try to ping your default gateway. Three commands you can use are:. Localhost is a reserved host name that maps to a reserved IP address When you type ping localhost , the messages are local to your computer; no packets are sent to the network. If pinging localhost is successful, you receive four replies from IP address If the ping command is unsuccessful you will receive a message that says local host is unknown.
Troubleshooting a Connection Using Tracert. If you can ping your default gateway but not a remote host, try the tracert trace route command. The tracert commands you can use are:. Document the information that the tracert command returns when the remote host is available.
Later, if the remote host is not available, you can compare the information returned by tracert at that time to the original tracert report and determine which gateway is unavailable.
Note If your organization uses a proxy server for access to the Internet, you may not be able to use ping or tracert for hosts outside of your intranet. Configuring Network Bindings. Because Windows 98 can support multiple network adapters, protocols, and services simultaneously, these network components need a way to interface with each other.
To do this, the components use a process called binding, which sets up communication between the components. Bindings are configured between network adapter cards and protocols, and between protocols and services. By default, all possible bindings are enabled, but you can optimise performance by modifying bindings. Here are some sample scenarios:. Disabling the unused bindings can improve your computer's performance slightly.
Disabling the unused binding may improve your computer's performance slightly. You can make NetBEUI your default protocol by selecting the default protocol option on the Advanced tab in the Properties dialog box for that protocol see Figure 8.
The default protocol overrides other protocols when your computer attempts to establish a session with a remote computer. To optimise performance, you should make the protocol you use most often your default protocol.
To improve performance when you have multiple adapters and protocols, you can modify bindings between adapters, protocols, and clients. If you want to configure the bindings for a network component, perform the following procedure:. On the Configuration tab, choose the adapter or protocol whose binding you want to modify. Click Properties and select the Bindings tab. Select the appropriate bindings.
To use Windows 98 networking features, you must first give your computer a unique name that other computers on the network will recognize. You then install the hardware and software that enables your computer to connect to the network, and configure the protocol that your computer uses to communicate with other computers on the network. Sharing Windows 98 Resources.
To share resources on a Windows 98 network, you must set up your computer and other computers so that they can function in a shared environment. This lesson discusses sharing Windows 98 resources, including files and printers. Installing Client for Microsoft Networks. On a Microsoft network, you must have Client for Microsoft Networks installed in order to enable file and printer sharing. With Client for Microsoft Networks installed, you can enable sharing, and you can modify the properties of folders and printers in order to share them.
Client for Microsoft Networks is a bit, protected-mode network client for Windows 98 that provides network functionality for Microsoft operating systems, including:. Client for Microsoft Networks can use any combination of the following protocols:. If the setup program detects your network adapter during setup, the program installs Client for Microsoft Networks by default. You can also install and configure Client for Microsoft Networks manually.
If you want to install and configure Client for Microsoft Networks, perform the following procedure:. The Select Network Component Type dialog box appears.
Click Client and click Add. The Select Network Client dialog box appears see Figure 8. Click Microsoft , and then click Client for Microsoft Networks. After installing Client for Microsoft Networks, you can allow other computers on the network to access shared data on your computer by enabling file and printer sharing for Microsoft Networks. Configuring Microsoft File and Printer Sharing. After you have configured network connectivity, you can share resources among the Windows 98 computers on your network by installing File and Printer Sharing for Microsoft Networks.
You can configure file and printer sharing using Control Panel see Figure 8. In order for Samba to allow you access to its shares, the username and password you give to Windows must match the account and password on the Samba server. If you don't have this tab in your dialog box, don't worry; it's probably because you haven't given yourself a Windows username and password yet.
Simply click the OK button at the bottom and respond Yes when Windows asks to reboot. Then, skip down to the section entitled Section 3. After selecting the Change Passwords tab, the dialog box in Figure 3. Select the Change Windows Password button. The Change Windows Password dialog box should appear, as shown in Figure 3. From here, you can change your password to match the password of the account on the Samba server through which you intend to log in.
If you didn't have a Change Passwords tab in the Passwords Properties window, then after Windows has finished rebooting, it will ask you to log in with a username and a password.
Give yourself the same username and password that you have on the Samba server. After confirming your new username and password, or if you already have one, Windows should ask you if you want to have a profile, using the dialog shown in Figure 3. Answer Yes, upon which Windows will create a separate profile and password file for you and save a copy of your password in the file.
Now when you connect to Samba, Windows will send its password, which will be used to authenticate you for each share. We won't worry about profiles for the moment; we'll cover them in Chapter 6, Users, Security, and Domains. We should point out, however, that there is a small security risk: someone can steal the password file and decrypt the passwords because it's weakly encrypted. In Windows NT 5. To do this, double-click on the Network icon in the Control Panel.
You should see the network configuration dialog box, as shown in Figure 3. By routing a protocol through a hardware device, the machine can act as a client or server for a particular type of network. If it appears similar to Figure 3. You may also see "File and printer sharing for Microsoft Networks," which is useful.
You can add the protocol by clicking on the Add button below the component window. Indicate that you wish to add a specific protocol by selecting Protocol and clicking Add After doing so, you will be returned to the network dialog. Click OK there to close the dialog box, upon which Windows will install the necessary components from disk and reboot the machine. When it is highlighted, click the Properties button. There are seven tabs near the top of this panel, and you will need to configure four of them:.
This will dISPlay a lot of information. If it scrolls off the top you may need to enlarge the window. Step 4: I want you to write down some of the information in this window. Make sure to note which is which. We are going to use this information a little bit later.
The name server entries are a bit complicated. Name Server is just another name for DNS domain name server server. Some router's act as a proxy between the actual name servers and your computer.
You will know when this is the case, because the Default Gateway will list the same ip address as the Name Servers entry. We need to have the correct Name Server IP addresses.
If we do not, you will not be able to browse the web. There are a couple ways to get these. The first way is to log into your router's web interface, and look at your router's status page.
Write down the ip adresses of your Name Servers. They should know the ip addresses of your Name Servers right off. If they ask you why you need them, you can tell them you are trying to setup a static IP address on your computer. If they try to sell you a static external ip address, don't buy it. That's an entirely different thing that what you are trying to setup.
Type exit in this window, then press the enter key to close it. Step 5: Right click Network Connections on the desktop, and then click the properties option. Step 6: You should see a list of options under the following components are installed. Click it when you find it, and then click properties. Step 7: Before you make any changes, write down the settings that you see on this page. If something goes wrong you can always change the settings back to what they were!
You should see a dot in the Obtain an IP address automatically box. If you do not, your connection is already setup for a static ip. Just close all these windows and you are done. Pick an ip address and enter it into the IP Address box.
The ip address you choose should be very similar to the router's ip addres. Only the last number of the ip address should be different. If the router's ip address is The ip address you choose should end with a number between 1 and , and should not be the same as the router's ip address. Every device that connects to your network needs to have it's own ip address.
