Introduction To Windows Networking
What is Windows Networking?
The term networking covers a broad range of the topics and technologies. A computer network is segmented into different parts to share the data and resourced between the different computers of a network. Microsoft has released the operating systems that have the networking capabilities so Microsoft Windows 98, Microsoft Windows 2000, Windows 2003, Windows XP Professional and Windows Vista all are the network operating systems. All these operating systems have built inn capabilities of files and printer sharing, security, network administrative control, protocols support such as TCP/IP, NetBIOS, IPX/SPX and network hardware support.
Naming Computers
All computers in a Windows based network requires a unique name for their identification i.e. the name of the computer A cannot be assigned to the computer B and so on. Assign a meaningful computer name to all the computers and the name should be easy to remember. All the names should be configured properly and ensure that the name is not longer than the 15 characters and they contain no spaces in them. Also try to avoid the special names while naming the computers such as / \ *,:,. To assign a computer name in Windows XP and Windows 2000 do the following things.
1. Right click on the My Computer.
2. Click Properties
3. Click on Computer name.
4. Assign a unique and meaningful computer name.
Naming Workgroup and Domains
A Windows based computer network can be a workgroup (Peer to Peer) or domain (client/server). You can make your computer a part of the workgroup or a domain. If you have centralized server then your computer will be part of the domain and if you have no server then all computers will be having peer to peer networking. In both cases, while joining your computer to a domain or a workgroup always assign unique, sequenced, memorable and meaningful names to the computers. Do not use duplicate names and the special characters such as / \ *,:,,. In order to join a computer to a domain or workgroup in Windows 2000 and Windows XP Professional do the following.
1. Right Click on My Computer
2. Click Properties
3. Click on Computer Name
4. In Workgroup or domain, enter the name of the workgroup or domain.
If everything is correct such as unique computer name, unique IP address, correct workgroup or domain name then you computer will be the part of the workgroup or domain in the few seconds and you will be see a welcome to domain or workgroup message and will be prompted to restart the computer name.
Files Sharing
Being on network computer files and printer sharing is a must. To enable the files and folder sharing in Windows XP Professional 2000 and Windows 2000 do the following.
1. Right Click on the folder name you want to share.
2. Click on the properties.
3. Click Sharing.
4. Click on Share this computer on the network.
5. Assign a shared computer name.
You can set the sharing rights for the users and also control the shared folder access by allowing and denying permissions to specific users or groups. If you want to share the individual files, you can put the files in the same shared folder. All the files and folders in the parent shared folder will be automatically shared.
Network Configurations Overview
A computer network can be configured and installed in different ways depending upon the requirements. If you are responsible for managing your computer network, securing and ensuring the uptime then you need a precise solution for your devices configurations. A network can also be configured, managed and administered through the third party software such as DeviceExpert that can be used to manage the switches, routers, firewall and computers in your network. Each device in a network such as computer, printer, scanner, switch and router is known as a node.
If you manage a big network then it is very important to store the configurations of each node so that you can view, store and use the same configurations any time. In Windows XP Professional, you can store and maintain multiple configurations for your home and office networks. Different vendors provide different network configurators and management software. These software allow the network administrators to save and view the network settings.
Some of the best network configurator programs are D-Link Network Configurator, PE Network Configurator, Rapid Network Configurator and DeviceExpert. In this article we will learn that how to configure the multiple services such as DHCP, DNS and devices as routers and LAN card in an Ethernet network. The following information is mandatory for configuring a computer network.
• Host Name of computers

What is a Printer?
Printer is a device that prints text, graphics and images on the paper. With regards to quality, graphics, speed there are different types of a printer. The most common types of the printer are Dot matrix, InkJet and Laser printer. In the following sections of this article we will discuss all the common types of printer.
Common Types of Printer
Dye Fusion Thermal
Thermal Dye sublimation or thermal dye transfer is a process that is used by the color printers. A color wax film is moved throughout the page and pigments are heated and deposited on the page.
Inkjet
Inkjet printers use spray and print them on the paper. They produce high quality prints and have better image quality and they are faster as compared to the DOT Matrix printers. Due to low cost, high quality and ease of use, they are most commonly used printers.
Laser Jet
Laser printers use xerographic printing process, which is a same technique as used by the photocopier machine. In the laser printer, the roller is charged with the electricity and the laser light is used to remove that charge from the roller. Laser printer is very fast and they produce high quality and text, graphics and images.
Dot Matrix
In the Dot Matrix, pins are used to strike the ribbon and dots, characters and images are produced when pin strikes the ribbon. The columns of 8, 9 and 24 pins are used in the Dot matrix. Dot matrix printers have horizontally moving head and pins in the vertical position. Dot matrix printers are mostly cheap and they are used for low to medium quality of printing.
LCD/LED
This is a type of printers that uses the liquid and light emitting diodes LED to produce the produce the images on the roller.
Camera Copy
Camera copy printers produce high quality full color output and the laser light is used to write on the film inside the camera. This type of printing process is expensive.
Line Printer
Line printers have horizontal drum that stretch the paper. The drum is made up of 132 thin cylinders and each have a complete set of characters.
Daisy Wheel

Troubleshooting the local area network means identifying and removing the network problems for getting the optimized performance. In order to troubleshoot the problem in the LAN, it is important to monitor the LAN to identify the problems. LAN monitoring can be accomplished with the network management computer or general network sniffers. Protocol Analyzer provides various LAN troubleshooting solutions over the TCP/IP networks.
LAN/TCP/IP troubleshooting can often be tricky and the troubleshooting scenarios includes finding duplicate IP addresses on the network computers, misconfigured network applications, non-optimized network devices, low service performance, cabling problems, faulty LAN cards and network switches, viruses and spyware attacks, misconfigured firewall, security issues, DNS/DHCP problems, proxy server’s settings and overloading of the network servers with the number of software applications.
The problems in the Local Area Network can be aroused by a number of reasons as mention above. Being a LAN/Network administrator it’s your responsibility that you are well aware of your LAN infrastructure, network hardware, software, user access rights and preferences and the major configurations of the network. The best practice is to make inventory of all the resources of your LAN such as number of workstations, software installed and network hardware.
Following section provides the useful tips in diagnosing and troubleshooting the most common problems in your LAN. Whenever you face connectivity issues, security issues and performance issues the following tips are helpful in diagnosing troubleshooting the problems.
Connectivity Issues
• First thing to check it to make sure that you have the same class IP address and the associated subnet mask in all the computers in your LAN.
• Make sure that you have provided the accurate gateway address on all the computers.
• Ensure that all the network cables are tightly plugged at both ends i.e. one end in the Hub/Switch and one in the LAN card.
• Make sure that the lights on the Hub/Switch and LAN card are ON and working.
• If you are behind a proxy server and facing internet connectivity issues, make sure that you have provided the accurate proxy server’s settings at the client computers.
• Check your firewall settings and make sure that the firewall is not blocking the incoming and outgoing traffic.
• Use the PING command at the common prompt to verify the connectivity with the other computer.
Example
At command prompt
Ping 100.100.100.1 and press enter (100.100.100.1 is the IP address of the other computer)
• If the connectivity issue is with the particular computer, reinstall the driver of the NIC adapter and if the problem is still there then change the NIC adapter and reconfigure it.
• If the connectivity problem still not resolved then check the network cable from computer to HUB/Switch
Security Issues
Security issues are more likely to occur in the LAN if no proper security mechanism, policies, antivirus programs and security methods have been implemented.
• Install up-to-dated antivirus and anti spyware program and regularly scan your network server all the computers in the network.
• In the proxy server block notorious applications that cause security issues in the network and define specific internet access rules for the users.

Windows 2000 Server Installation Overview
In this section you will learn the basicss of windows 2000 server installation, how to install window, active directory, domain controllers, system configurations. Being a network administrator or Microsoft Windows 2000 Server support professional, one of your job description tasks is Windows Server Installation.
Step #1: Planning for your installation
When you run the Windows 2000 Server setup program you must know that how to install the Windows 2000 server. Thorough planning can make you avoid potential problems during the installation process. So, it’s necessary to do some paper work and make a good plan before installing the Windows 2000 server operating system. You must know the needs of your office network, server hardware and software to be installed on your server.
Without a proper plan Potential problems can occur in the future and work can become more hectic.
There are some important points, which you should take into account before starting the installation process.
1. Check System requirement
2. Check hardware and software compatibility
3. Check the disk partitioning options
4. Select the file systems according to your needs.
5. Decide workgroup or domain installation
6. Complete a pre installation checklist.
Once you are making sure about these things you can start the installation process.
Step #2: Starting the installation process
You can install Windows 2000 Server in different ways, all the methods are valid and which method you choose is depends on your needs and limitations. Manual installation process can be divided into different ways as followings.
• Boot from CD- This is a fresh installation and no existing partition is required.
• Boot from the 4 setup disks and then insert the CD, in this way also not existing partition is required.
• Boot from an MS-DOS startup floppy disk, go to the command prompt, create a 4GB FAT32 partition with FDISK command, reboot the computer, format the C partition, you have created and then go to the CD drive, go to the i386 folder and run the Winnt.exe command.
• In the other methods, run an already installed operating system such as Windows NT 4.0 Server and from within the NT 4.0 go to the i386 folder in the Windows 2000 Server installation CD and run the WINNT32.exe command. This will upgrade the Windows NT Server 4.0 to the Windows 2000 Server.
• Alternatively, if you want to upgrade from Windows 98 into Windows 2000 Professional you can follow the same steps as I have described in the above installation method. But you cannot upgrade Windows 98 into Windows 2000 server.
Additionally, there are other automated installation methods, such as uninstallation method by using an unattended file, using Sysprep, using RIS or running the uninstallation method by the CD itself.
It doesn’t matter that which installation method you use to install Windows 2000 Server or Professional. All methods look alike and the main function is the same.
Step #3: Text based portion of the setup
The setup process starts loading a blue-looking text screen. In this way you will be asked to accept the license agreement EULA and choose a partition on which you want to install Windows 2000 and you will be also asked to format the partition if the partition is new FAT, FAT32 or NTFS. The setup process begins loading a blue-looking text screen (not GUI).
1. Select to boot the computer from CD.
2. At this stage you can press F6 if you need to install the additional SCSI adapters or other storage devices. If you choose it then you will be asked to provide the floppy disk for the drivers.
3. Setup will get all the required drivers and files.
4. Now select to setup Windows 2000. At this point, if you want to fix some problems in the previously installed operating systems then you will have to press R. If not, then just press enter to continue with the fresh installation.
5. If you haven’t made any partition then you will get a warning message to create a partition and delete the old partitions. You can specify the partition size here. If you want to continue then press C.
6. Accept the license agreement and press F8.
• Select or create the partition on which you will install W2K.
• If you hard disk is already partitioned but don’t have enough disk space for the installation, you can create an additional partition from the unpartitioned space. If the hard disk is already partitioned, but has enough unpartitioned disk space, you can create an additional partition in the unpartitioned space. If the hard disk already has a existing partition, you can delete it to create more unpartitioned space for the new partition. By deleting the old partition you will delete all data on that partition.
If you select a new partition during Setup, create and size only the partition on which you will install Windows 2000. After installation, use Disk Management to partition the remaining space on the hard disk.
7. Select the file system like FAT32, NTFS for the installation partition. After you create the partition, select a file system. After selecting the file system, it will ask you to format the disk. Windows 2000 supports FAT, FAT32 and NTFS file system. You can get access to the local data on your hard disk, if it is formatted with the NTFS and if your operating system is Windows Server 2003, Windows XP Professional, Windows 2000 and Windows NT. If you plan to get data on your local hard disk’s drive where Windows 95 or Windows 98 is installed then you will have to use FAT or FAT32 file systems.
8. Setup will then begin copying files after formatting the disk, from the installation point (CD, local i386 or a network share).
9. After copying files step is completed the computer will be restarted in the graphical mode.

How to Troubleshoot LAN
Troubleshooting the local area network means identifying and removing the network problems for getting the optimized performance. In order to troubleshoot the problem in the LAN, it is important to monitor the LAN to identify the problems. LAN monitoring can be accomplished with the network management computer or general network sniffers. Protocol Analyzer provides various LAN troubleshooting solutions over the TCP/IP networks.
LAN/TCP/IP troubleshooting can often be tricky and the troubleshooting scenarios includes finding duplicate IP addresses on the network computers, misconfigured network applications, non-optimized network devices, low service performance, cabling problems, faulty LAN cards and network switches, viruses and spyware attacks, misconfigured firewall, security issues, DNS/DHCP problems, proxy server’s settings and overloading of the network servers with the number of software applications.
The problems in the Local Area Network can be aroused by a number of reasons as mention above. Being a LAN/Network administrator it’s your responsibility that you are well aware of your LAN infrastructure, network hardware, software, user access rights and preferences and the major configurations of the network. The best practice is to make inventory of all the resources of your LAN such as number of workstations, software installed and network hardware.
Following section provides the useful tips in diagnosing and troubleshooting the most common problems in your LAN. Whenever you face connectivity issues, security issues and performance issues the following tips are helpful in diagnosing troubleshooting the problems.
Connectivity Issues
• First thing to check it to make sure that you have the same class IP address and the associated subnet mask in all the computers in your LAN.
• Make sure that you have provided the accurate gateway address on all the computers.
• Ensure that all the network cables are tightly plugged at both ends i.e. one end in the Hub/Switch and one in the LAN card.
• Make sure that the lights on the Hub/Switch and LAN card are ON and working.
• If you are behind a proxy server and facing internet connectivity issues, make sure that you have provided the accurate proxy server’s settings at the client computers.
• Check your firewall settings and make sure that the firewall is not blocking the incoming and outgoing traffic.
• Use the PING command at the common prompt to verify the connectivity with the other computer.
Example
At command prompt
Ping 100.100.100.1 and press enter (100.100.100.1 is the IP address of the other computer)
• If the connectivity issue is with the particular computer, reinstall the driver of the NIC adapter and if the problem is still there then change the NIC adapter and reconfigure it.
• If the connectivity problem still not resolved then check the network cable from computer to HUB/Switch
Security Issues
Security issues are more likely to occur in the LAN if no proper security mechanism, policies, antivirus programs and security methods have been implemented.
• Install up-to-dated antivirus and anti spyware program and regularly scan your network server all the computers in the network.
• In the proxy server block notorious applications that cause security issues in the network and define specific internet access rules for the users.
• Use strong passwords, encryption methods and limit the access to the network resources.
• Enable logging on all the network computers and server machine.
• Implement security policies.
• Update your operating system and install latest services packs and security patches.
• Clean computer’s registry with the excellent Windows registry cleaner software. An optimized an error free registry is required for the smooth functioning of the computer.
• Implement firewall on the gateway computer and it will save your computer from the unauthorized internal and external access.
The above tips will definitely help you out in resolving the security related issues in your LAN.
Performance Issues
The performance issues in the network occurs with the heavily installed applications, Windows registry errors, antivirus and anti spyware free systems, low or faulty hardware, low physical memory, unnecessary network shortcuts, simultaneous access to the server for the same resources and in the unmanaged network environment.
• Dividing the network in the subnets is helpful in load balancing and improving the performance.
• Remove unnecessary network shortcuts and it will increase the network browsing speed.
• Clear cookies, browser’s history and other temporary files.
• Increase the physical memory (RAM)
• Uninstall any unnecessary software applications from computers.
• Separately configure the proxy server, File server, Print server and Gateway computer to put the minimum load on each server.
• Install the LAN cards that support 10/100 Mbps speed and use Switch instead of Hub in the LAN.
opefully the above mentioned tips are helpful in resolving the most common connectivity, security and performance related issues in
Network troubleshooting means recognizing, diagnosing and isolating the problems in a computer network.

Network Troubleshooting Software
There can be different sorts of problems that can arose due to network malfunction in various hardware and software components of a network. Networks can be of different types. From home to corporate Networks, each network type has its own errors and remedies. A simple Network troubleshooting starts from pinging your nearest IP address in your subnet. You should try to ping local host from command prompt. The address for local host is 127.0.0.1 and then tries to ping your own IP Address. If both loopback adapter and Network interface return true (send replies) then assume your own physical pc is ok.
To check the connectivity of other computer(s), try to ping them and find out about their connectivity. There can be many methods and software techniques to resolve network issues.
You can check your network card’s hardware status to find out its connectivity. There are certain permissions checking techniques that can be used for network diagnostics. “Netsh” command in windows offers many measures to locate problems in Networks.
To resolve connectivity issues, you must check the gateway and DNS settings. In advanced settings, you can also set the WINS server, which stands for Windows Internet Naming Server.
SNMP (Simple Network Management Protocol) is a valuable tool for Network Diagnostics through SNMP Strings. It can not only check the status of each node.
You can not only check status of each connected node but can set certain triggers and alarms against specific actions or lost connectivity in the network.
Besides SNMP, in a Domain Environment, you can use windows OS own commands to check for Network errors. First you must install afminpak.msi on Start>run and then use its commands liker “dcdiag” or “netdiag” to chweck for connectivity and validity of service operations.
Active Directory Administrative Management (ADAM) can also be used to detect and diagnose the problems ion Active Directory Structure.
In case of a broadband connection, you must first verify the settings provided by Service Provider and check them against your own settings. Then verify the physical connectivity between both ends.
Most of the times, the errors are in drop line also known as local loop. Sometimes there are hardware errors in Modem or Router which must be addressed by a physical replacement of equipment.
All the Network Management Software can detect errors in Network and help to locate the faulty node in Network which will in turn facilitate greatly in Network troubleshooting.
