ENDS WINDOWS XP SP3 AND OFFICE 2003
Windows XP SP3 and Office 2003
Support Ends April 8, 2014
WHY?
Why is Microsoft ending support for Window XP and Office 2003?
In 2002 Microsoft introduced its Support Lifecycle policy
based on customer feedback to have more transparency and predictability
of support for Microsoft products. As per this policy, Microsoft
Business and Developer products, including Windows and Office products,
receive a minimum of 10 years of support (5 years Mainstream Support and
5 years Extended Support), at the supported service pack level.
Windows XP SP3 and Office 2003 will go out of support on April 8, 2014, if your organization has not started the migration to a modern PC, you are late. Based on historical customer deployment data, the average enterprise deployment can take 18 to 32 months from business case through full deployment. To ensure you remain on supported versions of Windows and Office, you should begin your planning and application testing immediately to ensure you deploy before end of support.

Creating a User Template
Users in a domain often share many similar properties. For example, all Managers can belong to the same security groups, log on to the network during similar hours, and have home folders and roaming profiles stored on the same server. When you create a new user, you can simply copy an existing user account rather than create a blank account and populate each property.
.gif)
Right click the OU where the template is to be created. Select New>User. Fill in the details, using the underscore character at the start of the username ensures the template will be at the top of the list. Click Next. Type in password and select User must change password at next logon. The template account should not be used to log on to the network, ensure Account is disabled option is selected. Click Next to continue. Click Finish.
A user account template is a generic user account prepopulated with common properties. For example, you can create a template account for Managers that is preconfigured with group memberships, logon hours, a home folder, and roaming profile path.

Troubleshooting DNS
Troubleshooting DNS
NSLOOKUP is an important utility that performs query testing and troubleshooting of DNS servers at the command prompt window. NSLOOKUP can be accessed by going to the command prompt window and typing in NSLOOKUP and pressing Enter.As shown, the NSLOOKUP tool is now active. To do a forward or reverse lookup, type the name in the command prompt window. A list of command lines can be found by typing in help or ? From the NSLOOKUP command window.
When a query is made to a DNS server, the server can either return an authoritative answer or a non-authoritative answer. If it returns an authoritative answer then the record exists in its own zone file. If it returns a non-authoritative answer then the record exists in the zone file of another DNS server.
There are many ways that DNS can fail to work. There is no one sure way to solve every problem which might occur. The following list is a reasonable starting point for troubleshooting.
- Test to see if the client is on the network by using the “ping” utility.
- Use “ipconfig” to view the clients DNS settings.
- Use NSLOOKUP to perform DNS queries and check the contents of the zone files.
- Use the Event Viewer to see any DNS client or server error messages.
- From the server Properties choose the Logging tab to log and monitor certain events.
- From the server Properties choose the Monitoring tab to perform simple test queries.
- From the DNS console select Action and choose Set Aging/Scavenging to clear the DNS database of stale resource records.
Windows
Microsoft Windows
The oldest of all Microsoft’s operating systems is MS-DOS (Microsoft Disk Operating System). MS-DOS is a text-based operating system. Users have to type commands rather than use the more friendly graphical user interfaces (GUI’s) available today. Despite its very basic appearance, MS-DOS is a very powerful operating system. There are many advanced applications and games available for MS-DOS. A version of MS-DOS underpins Windows. Many advanced administration tasks in Windows can only be performed using MS-DOS.
The
history of Microsoft Windows dates back to 1985, when Microsoft
released Microsoft Windows Version 1.01. Microsoft’s aim was to provide a
friendly user-interface known as a GUI (graphical user interface) which
allowed for easier navigation of the system features. Windows 1.01
never really caught on. (The amazing thing about Windows 1.01 is that
it fitted on a single floppy disk!). In 1987 Microsoft revamped the
operating system and released Windows 2.03. The GUI was very slightly
improved but still looked too similar to Windows 1.01. The operating
system again failed to capture a wide audience.Microsoft made an enormous impression with Windows 3.0 and 3.1. Graphics and functionality were drastically improved. The Windows 3.x family provided multimedia capabilities as well as vastly improved graphics and application support.
Building on the success of Windows 3.x, Microsoft released Microsoft Windows For Workgroups 3.11. This gave Windows the ability to function on a network. It is not uncommon to find companies still using Windows 3.11.
In 1993 Microsoft divided the operating system into two categories; Business and home user. Windows NT (New Technology) was a lot more reliable than Windows 3.x. Windows NT provided advanced network features. On the business front, Windows NT continued to develop with the release of version 3.51. Different versions were provided which offered different functionality. Server provided the higher network functions and Workstation was mainly for the client machines.
In 1995 Windows went through a major revamp and Microsoft Windows 95 was released. This provided greatly improved multimedia and a much more polished user interface. The now familiar desktop and Start Menu appeared. Internet and networking support was built in Although Windows 95 was a home user operating system, it proved to be very popular in schools and businesses.
After the success of Windows 95, Microsoft improved the GUI interface of Windows NT and released Windows NT 4.0. NT4 could be tailored to the size of the business, NT4 Server for small to medium sized businesses and Enterprise Server for larger networks. Microsoft continued to improve the Windows format. Although Microsoft Windows 98 was very similar to Windows 95, it offered a much tidier display and enhanced multimedia support.
Although Windows 2000 had a greatly improved user interface, the best of the enhancements appeared on the server side. Active Directory was introduced which allowed much greater control of security and organisation. Improvements to the overall operating system allowed for easier configuration and installation.
One big advantage of Windows 2000 was that operating system settings could be modified easily without the need to restart the machine. Windows 2000 proved to be a very stable operating system that offered enhanced security and ease of administration.
The last incarnation of the Windows 9x family was Windows Millennium Edition (ME). There were many different versions of Windows floating around at this stage that Microsoft decided the next release of Windows would consolidate both the business and home versions. Although Windows ME was visually similar to Windows 2000. Windows ME was based on the Windows 9x line. Windows 9x/ME systems are not as secure and stable as Windows NT and 2000 systems.
Because of the stability of Windows NT/2000, Microsoft decided to end the development of the Windows 9x line, and merge both the consumer and business products. Microsoft Windows XP comes as the Home Edition and Professional, each is based on Windows 2000. Windows 2000 Server has been upgraded to Windows 2003. This appears in four variants: Web Server, Standard Server, Enterprise Server and Datacenter Server, each fulfilling a different business role. Windows XP has a very polished look, but the overall functionality is very similar to Windows 2000.
Operating Systems
The most important piece of software on any computer is the operating system. The operating system gives the framework upon which all other services and applications run. The majority of home users use a Windows based machine. Most of today’s applications and games are designed to run solely on Microsoft systems.Microsoft Windows is extremely popular in schools and colleges, many businesses also use Windows.
Other Operating Systems
The Windows family is the most widely used Operating System. There are other operating systems in the computing world, and some are a lot older than Microsoft Windows. Luckily most operating systems can interoperate with each other. Many of today’s larger networks contain a variety of operating systems.UNIX
A big advantage of UNIX is that it can be run on nearly every computer hardware platform including Apple Macintosh machines. The UNIX operating system is one of the oldest and most powerful operating systems. It was developed by Bell Laboratories. There are many variants of UNIX available.Novell NetWare
Novell NetWare is an advanced network operating system. It has an advanced directory service structure similar to Microsoft’s Active Directory. Fortunately both directory services are interoperable as both directories use the x500 directory service standard.Linux/FreeBSD
Two of the most popular variations of UNIX come in the form of Linux and FreeBSD. A big advantage of both Linux and FreeBSD is that they are both open-source, that is, any user can contribute to the development of the OS. Versions of both operating systems are completely free.Linux and FreeBSD can easily take the role of a server or client machine. However, they are considered to be more difficult to master as both utilize the command line rather than a user friendly GUI. There are several different distributions of Linux, but for each the underlying operating system remains the same.
Apple Macintosh machines offer high performance sound and graphics editing and are therefore extremely popular in the design industry. Apple have developed their own operating system, the newest version of which is the Mac OS X, which is based on UNIX.
Mac OS X is a very user friendly operating system and is increasingly popular for home PCs.

Remote Desktop Connection?
Remote Desktop Connection is a technology that allows you to sit at a computer (sometimes called the client computer) and connect to a remote computer (sometimes called the host computer) in a different location. For example, you can connect to your work computer from your home computer and have access to all of your programs, files, and network resources as though you were in front of your computer at work. You can leave programs running at work and then, when you get home, you can see your work computer's desktop displayed on your home computer, with the same programs running.Illustration of two computers connected by a Remote Desktop connection, allowing access from one to the other remotelyA Remote Desktop connection between two computers

Video game

A video game is an electronic game that involves human interaction with a user interface to generate visual feedback on a video device. The word video in video game traditionally referred to a raster display device,[1] but following popularization of the term "video game", it now implies any type of display device. The electronic systems used to play video games are known as platforms; examples of these arepersonal computers and video game consoles. These platforms range from largemainframe computers to small handheld devices. Specialized video games such asarcade games, while previously common, have gradually declined in use. Video games have gone on to become an art form and industry.
The input device used to manipulate video games is called a game controller, and varies across platforms. For example, a controller might consist of only a button and a joystick, while another may feature a dozen buttons and one or more joysticks. Early personal computer games often needed a keyboard for gameplay, or more commonly, required the user to buy a separate joystick with at least one button.[2] Many modern computer games allow or require the player to use a keyboard and a mouse simultaneously. A few of the most common game controllers are gamepads, mice, keyboards, and joysticks.
Video games typically use additional means of providing interactivity and information to the player. Audio is almost universal, using sound reproduction devices, such as speakers and headphones. Other feedback may come via hapticperipherals, such as vibration or force feedback, with vibration sometimes used to simulate force feedback.
In the early days of cartridge consoles, they were sometimes called TV games.

History
Main article: History of video games
See also: First video game
Early games used interactive electronic devices with various display formats. The earliest example is from 1947—a "Cathode ray tube Amusement Device" was filed for a patent on January 25, 1947, by Thomas T. Goldsmith Jr. and Estle Ray Mann, and issued on December 14, 1948, as U.S. Patent 2455992.[3]
Inspired by radar display tech, it consisted of an analog device that allowed a user to control a vector-drawn dot on the screen to simulate a missile being fired at targets, which were drawings fixed to the screen.[4]
Other early examples include:
- The NIMROD computer at the 1951 Festival of Britain
- OXO a tic-tac-toe Computer game by Alexander S. Douglas for the EDSAC in 1952
- Tennis for Two, an interactive game engineered by William Higinbotham in 1958
- Spacewar!, written by MIT students Martin Graetz, Steve Russell, and Wayne Wiitanen's on a DEC PDP-1 computer in 1961.
Each game used different means of display: NIMROD used a panel of lights to play the game of Nim,[5] OXO used a graphical display to play tic-tac-toe [6] Tennis for Two used an oscilloscope to display a side view of a tennis court,[4] andSpacewar! used the DEC PDP-1's vector display to have two spaceships battle each other.[7]
In 1971, Computer Space, created by Nolan Bushnell and Ted Dabney, was the first commercially sold, coin-operated video game. It used a black-and-white television for its display, and the computer system was made of 74 series TTLchips.[8] The game was featured in the 1973 science fiction film Soylent Green. Computer Space was followed in 1972 by the Magnavox Odyssey, the first home console. Modeled after a late 1960s prototype console developed by Ralph H. Baer called the "Brown Box", it also used a standard television.[4][9] These were followed by two versions of Atari's Pong; an arcade version in 1972 and a home version in 1975 that dramatically increased video game popularity.[10] The commercial success of Pong led numerous other companies to develop Pong clones and their own systems, spawning the video game industry.[11]
A flood of Pong clones eventually led to the video game crash of 1977, which came to an end with the mainstream success of Taito's 1978 shooter game Space Invaders,[12] marking the beginning of the golden age of arcade video games and inspiring dozens of manufacturers to enter the market.[12][13] The game inspired arcade machines to become prevalent in mainstream locations such as shopping malls, traditional storefronts, restaurants, and convenience stores.[14] The game also became the subject of numerous articles and stories on television and in newspapers and magazines, establishing video gaming as a rapidly growing mainstream hobby.[15][16] Space Invaders was soon licensed for the Atari VCS (later known as Atari 2600), becoming the first "killer app" and quadrupling the console's sales.[17] This helped Atari recover from their earlier losses,[18] and in turn the Atari VCS revived the home video game market during the second generation of consoles, up until the North American video game crash of 1983.[19] The home video game industry was revitalized shortly afterwards by the widespread success of the Nintendo Entertainment System,[20] which marked a shift in the dominance of the video game industry from the United States to Japan during the third generation of consoles.[21]
