Thinstation mainly used in the school,office ,company and department. User can be used at the home..thinstation can be running XP on my workstation in the room..Thinstation is based on the linux .thus ,all user actually never see the Linux..we are decide to directly connect with Microsoft Window ,Citrix and Unix sever..the user can be feel due to the direct running on the server..but we need to have the local Desktop interface,local Browser and other devices..Thin station support the Miicrosoft Window and their environment .thus we can require unix and Linux ..
Thinstation can be run with the ordinary PC that have hardware (x87). We may either older computer or can be save the a lot of time on the workstation administration . An old modern of Penium 100 MHz with 32 MB RAM and the life of battery are very long and perfactly useful in workstation.If we use ,don't need a hard disk and we can made the boot off the network.The supported device of workstation are floppy disk ,Hard Disk ,CD and USB..
Installation of Microsoft
Winndows server versions are not much more difficult to install than Window XP or Vista. The first step is to choose the method. There are two kinds of installation method. They are -
Complete baseline installation or use existing OS
Network or local installation
Complete baseline installation or use existing OS
The new computer without an existing OS require drive partitioning and a fully compatible CD-ROM. An existing OS might require no new partitioning and can use an unsupported CD-ROM.
Network or local installation
We can store the Windows distribution files on a network-shared CD or directory;however, this method requires that the computer have a network-compatible OS already running. A local installation forces the distribution files to be pulled from a local CD-ROM drive or copied to a local hard drive.
No matter which installation method we use, both options require running Winnt.exe (or) Winnt 32.exe to start the setup process. After running Winnut or Winnt 32, the installation begins with a text-based phase. During this phase, we configure hard drives, format file systems, confirm the license agreement and define the name of the system directory. After this phase has been completed. The computer then restarts in the graphical user interface (GUI) phase of setup.
During this phase, we define the computer and domain names, enter the identification key from the installation CD, select the server types as a domain controller or a member server, assign a password to the Administrator account, and select environment and desktop components. Setup copies some files from the temporary folder to the destination folder and then moves into the network setup phase.
Linux installation is similar to the other NOS installations. We can install most Linux distributions easily from CD. The Linux Fedora Core 4 CD-ROM distribution come on four CDs. To begin the installation start the computer with CD1 inserted. The text based setup screen appears. Two installtion modes are available : text and graphical. Graphical is the default mode and is started by pressing Enter. To use text mode, type "Linux text" at the boot prompt. When installing Linux, we can choose one of four modes. Personal Desktop, Work station, Server or Custom. Based on we choice, the installation program installs the most appropriate services and application for that mode.
Linux developers have always been concerned about security, so they developed a built-in firewall for the Linux OS. During installation of Linux, we can selected the level of the firewall's operation.
Implementing of Multivendor Solutions
Nowadays, typical network environment we must connect computers and networks from different venders and provide remote as well as local network access. One of the biggest trials of a network administrator's job involves connecting systems that use different vendor's network operating systems. To make a multivendor environment work effectively, the server's operating systems, the client operating systems, and the redirectors must be compatible. A good example is an environment in which one computer run Window XP or Window Vista with the client for Microsoft networks, one computer runs Linux with Samba, one client runs Mac OS and the server runs Window Server 2003. Nation to linux and UNIX is the Network File System (NFS).
Many NOSs are available from vendors such as Sun, SCO, and IBM. This can be focuses on the four most popular PC operating system product vendors : Microsoft, Linux, Novell and Apple.
Multivendor Networking Environment
Multivendor Networking Environment means that there are oe more vendors who they manage and provide and also maintain the Network Environment but with different roles.Today's networks include computers and equipment from various vendors.Many NOSs are available from vendors such as Sun, SCO and IBM.The four most popular PC operationg system product vendors are Microsoft,Linus,Novell and Apple.
Every distribution of Linux includes a wealth of network services which include an implication of Network File System (NFS). NFS prmits networked machines to export protions of their local file systems and make them available to authorized users else where on the network. NTS also supports printer sharing , but its file and print services appear most commonly in multivendor networks where PCs are in the minority and the Linux OS predominates . Enablng PC clients to access NFS requires adding sortware to those clients; many Linux administrators prefer to add theSamba service to their Linux servers instead. Samba is the preferred service to interconnerct Windows clients with Linux servers instead. Samba is the pre ferred service to inter connect Windows clients with Linux hosts.

Total Cost Of OwnerShip (TCO)
Cost of Ownership
This section examines the four major cost components of client-server computing, the TCO concept, and three potential TCO models.
Cost Components of Client-Server Computing
To fully analyze distributed client server technology and its overall effect on cost, the cost of ownership must first be defined. Client-server cost of ownership is defined as the total cost of computing over a specified period of time and includes all the elements in delivering the information users want when it is needed.
Client-server computing costs consist of the following four major categories:
The first component, "hardware," is becoming the most cost-effective part of the total cost of ownership equation. Hardware costs vary, depending on the type of network operating system, the desktop operating system and the user's applications. Hardware costs can be grouped into two major categories - the client machine and the server machine. The client machine includes the acquisition cost of the equipment, and capital cost components such as memory upgrades, hard disk drives, backup equipment, adapter cards and cabling. The server machine includes many of the same acquisition costs associated with the client system, but also includes costs for port controllers, bridges/routers, WAN equipment, and line charges/T I links. In addition to the capital acquisition costs, several intangible hardware costs also need to be considered such as asset life, support availability, ease of use and resale value. Capital expenditures are typically the most readily identifiable cost component of the TCO equation.
Unlike centralized mainframe systems, client-server software costs are more difficult to identify due to the distributed computing environment. Software costs generally include the network operating system, client operating system, applications being deployed (personal, horizontal, and business applications), backup software, and essential network services such as directory services, messaging, routing security, and network management. Depending upon the client/server network deployed software applications may reside both on the network system and on the client machine. For example, an organization that has deployed a networked suite of applications may have client machines with duplicate software installed for remote access or non-network access. Software applications are more difficult to identify since they generally are installed locally on the client machine.
Both hardware and software only account for a fraction of the overall costs, while support costs can make up the majority of the cost of owning a client PC's - server system. Potentially, up to 75% of network ownership costs consist of personnel support costs and not technology costs. Thus, identifying and reducing support costs is more important than reducing hardware and software costs.
Support costs may include, but are not limited to the following:
Installation (hardware, software, cabling)
Training (IT staff, end-users)
Help desk support
Maintenance (assign shared resources, upgrades/fixes)
Change Security (add users, delete users, change users)
Planning/Design/Coding (network, implementation/distribution, application, upgrade/fixes)
Troubleshooting (application administration)
Network Administration (network planning, implementation, performance/change management and capacity planning)
Hidden costs can account for as much as 25% of the cost of owning a network. Hidden costs typically include "shadow staff" for support, floor space opportunity costs, power and cooling costs, transportation, travel, and user difficulty with tools, turnover, and time off for training. It is extremely difficult to quantify those costs traditionally outside the MIS arena. For example, "shadow staff" or co-worker support, will continue and not account for the overall cost until the client user views the formal support areas (i.e., help desk support) as a value-added service. These opportunity costs must be identified and addressed if client-server system costs are to be effectively assessed.
What is the thin client Network
The thin client computer contains information to start up and connect to network server. The thin server will not even have a hard ware. If the thin client computer needs to use a program, it will connect to the network server computer to do .
A thin client is much more simple than a complete computer. It is more cost to have one network server computer and many inexpensive thin client computers, than to have many complete computers. The thin clients are relatively simple, it is easier to solve problems and repair them. A standard computer has a lot of parts, and a thin client devices have a few parts.
A thin client is not the right tool for every job, it has many value and cost. If a user only needs to perform select tasks and does not need all the functionality of a standard computer or program.
(3.2) Network computer or Thin Client
Thin client benefit and disadvantages
Many servers and client PC's are often highly under-loaded. Virtual computing technology is taking huge advantage of this and thin clients can too. Take advantage of that unused load and save money from unnecessary equipment and make the most of the money you have spent. Savings can always be put back into the network by securing and enhancing the infrastructure making it even more reliable.There is a range of Thin Client devices
Feature of thin client
In thin client, hardware and software runs application on a server, but not on desktop. We will use key strokes and mouse click when we are sent over network to the server to process and give back the result. No need of Hard Disk Drive, floppy Disk Drive, CDROMS, Cooling Fans and very low Processing Power.
Work of thin client
Thin client can work as same as desktop PC and the speed too.
It supports Graphical User Interfaces and windows Entertainment.
It can be configured on as low as 16 Mb of RAM.
Works on either Citrix's ICA or Microsoft's Remote Desktop Protocols(RDP).
User logs on to the server via web portal and a familiar windows base environment is replicated on to users screens with access to Application, Internet, Mail, Drives, Printers, and so on.
Security of Thin Client
There isn't much that can be changed on a thin client and they aren't as appetizing to thieves as desktop PC's. Network bandwidth is reduced often to a more manageable level. Also, important data can be kept away from the main network and kept in the computer room - only screen and keyboard data needs to be sent over the cable. Keeps data where it should be - in a central location instead of it being dispersed around the network on different computers. Remote works can also benefit from rapid deployment of remote thin clients and the IT team can be safe in the knowledge that very little can happen to the home based workers.
Thin Client Advantages
The advantages of using the thin clients devices numerous. Thin client using results in lower costs and greater security. All processing occurs on a server and central managed, the local environment is stateless and the hardware have fewer points of contact and lower probability of error.
Thin Client Disadvantages
The disadvantages of thin clients can be understand as the advantages of thick clients. For example, thin client servers require a high performance level, since this is bulk of processing takes place. In contrast, thick clients perform of their own processing on their end and sending it to the servers. Therefore, thin clients servers very expensive and complicated.
Main Advantages of a Thin Client Network.
â€¢ Highly reliable system that delivers dependable computing for schools
â€¢ Technical issues are minimised for teachers, as they are centralised on a server(s)
â€¢ Limited risk of virus attack- as virus management is centrally controlled on servers(s)
â€¢ Standard personal desktop, programmes and data files available from any login point
â€¢ Small silent thin client computers that consume less energy and produce less heat
Main Disadvantages of a Thin Client Network.
â€¢ As the server(s) is critical to the operation of all computers on the network, there is a higher impact to the school if the server(s) fails. A redundant application server (i.e. a second server) is required in case of failure with the main application server.
â€¢ A higher level of planning is required to ensure that all parts of the system work properly together, hardware, software etc.
â€¢ Technical expertise is more specialised and as a result may be more expensive.
â€¢ All computers need to be connected to a thin Client server in order to operate. Standalone PCs cannot avail of server based learning applications
Drawbacks of thin clients
Thin client is not cure-all
Terminals are not meant for heavy tasks involving much computation (for exampke, AutoCAD or other modulation systems) or those which generate heavy traffic towards a client. In the first case, it can be explained by a very high load of the server, and in the second case it's connected with the network throughput. In this case it's better to use separate workstations. By the way, modern 3D games belong to both categories.
Server costs high price
Terminals lower cost is made up for by a high price of a server. A server must be powerful enough to be able to process tasks of all thin clients. However, the dependence of server's power on the number of working clients is not linear. Most typical tasks (for example,serveral copies of MS Office in the memory ) use libraries of the first copy started that is why the need in RAM is lower.
Everything works on a single computer-server
It is necessary to take all measures to ensure error-free operation and data integrity.
Steady communication channel
In some cases a workstation doesn't need a steady, especially fast, communication channel. A terminal needs permanent connection with the server.
Network Infrastructure is a set of hardware and software components used to interconnect computers and users. Infrastructure includes the transmission media, including telephone lines, cable television lines, and satellites and antennas, and also the routers, repeaters, and other devices that control transmission paths. In other words, you can say that Network infrastructure refers to physical and logical components that interconnect the hardware and software. The purpose of Network Infrastructure Plan is to establish the wide and local area network hardware, software, and maintenance. The primary goal of setting network infrastructure is as follows:
Cost effective use of networks, equipment and software
Productivity in sharing data
Reliability of networks and equipments
Training and support to users of technology
NetBIOS: NetBIOS provides two communication modes: session and datagram. Session mode lets two computers establish a connection, allows larger messages to be handled, and provides error detection and recovery. Datagram mode is connectionless. In this mode, each message is sent independently, so the messages must be smaller. In the datagram mode, the application is responsible for error detection and recovery. Datagram mode also supports the broadcast of a message to every computer on the LAN. NetBIOS provides services for the Name service for name registration and resolution, and for the Session service for connection-oriented communication. NetBIOS names are 16 bytes long, and there are very few restraints on the byte values that can be used. Non-alphanumeric characters can be used, but with some limitations and constraints.
Windows Internet Name Service (WINS) is a name resolution service that registers and resolves NetBIOS names to IP addresses used on the network. WINS is a Microsoft standard and is used to centralize the process of registering and resolving NetBIOS names to IP addresses.
In Windows Server 2003, computers can be grouped into workgroups and domains. Computers working in Windows workgroup environment use the NetBIOS naming system to name computers and resolve the names. In a workgroup, every computer is the master of itself. In Windows NT/2000/2003, a domain is a set of network resources that are part of a network and share a common directory database. A domain is administered as a unit with common rules and procedures. Each domain has a unique name. Users just have to log on to a domain to access the network resources within it. Members of the same domain can utilize the resources of that domain. However, these resources can also be shared between domains.
Dynamic Host Configuration Protocol (DHCP): DHCP is a service provided by DHCP servers. It dynamically assigns TCP/IP addresses to the clients on a network. It is a TCP/IP standard, which reduces the complexity and administrative overhead of managing a network. It prevents an administrator from manually configuring static IP addresses for individual resources. The default configuration for a computer running Windows Server 2003 is to automatically obtain an IP address from a DHCP server.
The DHCP service enables a computer to function as a DHCP server and configure DHCP-enabled client computers on a network. DHCP, which runs on a server, enables automatic and centralized management of IP addresses and other TCP/IP configuration settings for the network's client computers. A DHCP server must be authorized within Active Directory before it can lease IP addresses to DHCP clients.
Name resolution is handled in the network by NetBT broadcasts to the network segment. Common Internet File System (CIFS) is used to provide file sharing, security for network shares, network browsing, and printing within the workgroup.
You can view the advanced connection settings from the Advanced Settings dialog box. The Provider Order tab of the Advanced Settings dialog box displays the order in which various network providers, such as a NetWare, Microsoft Windows Network, or Microsoft Terminal Services, will be attempted. By default, Microsoft Terminal Services is given priority over other network connections. The Management and Monitoring Tools component allows you to manage and monitor devices on TCP/IP networks. You can capture and analyze packets over a network. The optional services can be added to existing Windows Server 2003 computers by using Add/Remove Programs or the Windows Server 2003 Configure Your Server Wizard, or by creating a customized automated installation of Windows Server 2003.
Vendor of Linux and Microsoft
Linux has many advantages of the devices as an operating system over competing systems such as Microsoft Windows.
Security - Linux is one of the most secure of operating systems, largely to harmful viruses that can cause expensive and distracting system interruptions. A Linux system has internal 'walls' built up so that unwanted visitors and viruses do not have broad access to the entire system. All files and directories have read, write, and execute privileges for the owner, the owner's workgroup, and all others. The Linux community aggressively maintains these 'walls' and all other aspects of Linux security.
Speed - Linux servers typically can handle several times as many users as other proprietary ones using the same hardware. Linux can take advantage of the latest processors and even use several of them at the same time for incredible speed. Furthermore, Linux supports true multi-tasking, which is the ability to run more than one program at the same time. It is therefore much more natural for the system to be doing many things at the same time without the 'flaking out' that one finds with the Microsoft operating systems.
Best Technical Support - Linux has the best technical support available. Linux is supported by commercial distributors, consultants, and by a very active community of users and developers. In 1997, the Linux community was awarded InfoWorld's Product of the Year Award for Best Technical Support over all commercial software vendors. Furious Net Solutions provides around-the-clock support for Linux with highly-trained, expert technicians.

A thin client network consists of the following four elements:
Terminal Services Server
Microsoft Windows Server 2003 R2
Client Devices Setup
Thin Clients ( NC )
Network Infrastructure Setup
Local Area Network(LAN)
Switch and UTP Cable
Server Based NOS
Microsoft and Linux
The central server of a thin client network is often called the terminal server. It is a powerful, high specification machine and capable of handling a large number of logged-in clients. It should:
â€¢ Have a multi-processor system (i.e., have two or more processors)
â€¢ Possess is a minimum of 40MB of memory (RAM) for each client on the system
â€¢ Possess an additional 500MB of memory for the operating system of the thin clients
â€¢ Have a large storage capacity and space as all information will be stored on the server
â€¢ Have located in a secure locked room and accessible to the network administrator, as the entire client systems depend on it for their computing power

Setup Server (Windows Server 2003)
Assuming that Windows Server 2003 is already installed on the server, go to Administrative Tools under the Start menu.
Choose "Terminal Server" and click "Next" twice to confirm
Close any open programs and click "OK".
The installation will continue for several minutes. After restarting and you log back in, a confirmation screen will appear that states that the computer is now a terminal server.
Click "Finish" Button.
You will be given a 120 day evaluation period to use unlicensed clients with Microsoft's Terminal Services. After 120 days, the clients will not be able to initiate a session and use Terminal Services.
In order for the licensing to take effect, Terminal Server Licensing will have to be installed on your machine. Go to the "Add/Remove" window in the Control Panel and find the "Windows Components Wizard" section. Click on "Terminal Server Licensing" and follow the installation instructions.
