404 ! 404 ! Whats it ?

Credits : Ron Eletrick

There are many Internet web server error messages. One such is the 404 error message. This error is a result of some problem with the Web server and not your terminal/computer. If you encounter a 404 error message, then the cause might be that the server is not able to locate the file that has been requested. It might be the case that the file that is sought has been moved to some other location or has been deleted. This causes a 404 error message to appear on you terminal screen.

Generally, when sending messages or requesting files using HTTP you get response from the server and each of this response has a numeric code associated with it. Here is a great technical site http://www.techiehut.com. Also this code has message in English that appears as the message along with the number. This message for a 404 error message will be “Not Found”. The usual scenario is that with a 404 error message a short HTML document which has the numeric code with the associated string is included. But not all the web browsers have this kind of facility. Some browsers are more user friendly in that they even have a humorous 404 error messages!

A 404 error will also occur and get displayed if the file that is requested is spelt wrong. Always see to it that you type in the correct spelling. Even if you have spelt it correct and you get a 404 error message, then possibly the file has been shifted or deleted altogether. One another alternative is to remove the information between each backlash. Try this until you land up with the required file. In many cases this helps to reach the information you need.

Microsoft Outlook Web Access has various kinds of 404 error messages. They can be “File Not Found”, “Not Found”, “Object not Found”, “Page cannot be found “ and a few others.

The possible causes for this error message to appear are DNS name resolution, proxy server configuration, exchange virtual directory configuration, Uniform Resource Locator (URL) creation, problem with URL Scan component of IIS(Internet Information Server) lockdown tool and/or the wrong port allocation on the OWA Web site.

Always keep in mind that there is way to find the page you require. A 404 error message just indicates that the wrong instructions have been given to the server to locate that page, similar to you being on the wrong route to reach a city. You just have to correct the route!

Windows Registry Structure

Credits : Kenth Nasstrom

You can view the structure of the Windows Registry when you open it up with a Registry Editor utility like REGEDIT.EXE or REGEDT32.EXE.

If you’ve never opened the Registry before, you might be surprised and comforted by its familiar-looking layout. Its hierarchical data structure is much like the data structure you see everyday in Windows Explorer, except here the tree structure units are keys, subkeys, and values rather than directories, subdirectories, and files. But any intuitive understanding of the Registry’s content (for most people) ends right here, because the registry was designed more for the operating system and installed applications than for humans.

The Registry’s hierarchical data structure and central location allow Windows and hosted applications to quickly locate their configuration settings and default parameters, but these parameters have values in the Registry that are different from their internally-defined values used by the applications themselves. This can make altering application settings from within the Registry a grueling and tedious task, and this is why most changes to Registry data are more easily (and more safely) made by changing settings from within individual applications or system utilities.

A Closer Look at Registry Structure

The primary divisions of the Windows Registry are seen a list of 4-6 expandable folders, called root keys or subtrees, in the left pane of the Registry Editor window. These can be expanded to show the keys and subkeys, and these can be expanded in turn to show further subkeys below or their value entries listed on the right pane in Registry Editor. The Registry subtrees and a description of their contents are as follows:

• HKEY_LOCAL_MACHINE (HKLM): This root key (or subtree) contains configuration data specific to the local computer, including its hardware devices and operating system components. The information contained within HKLM is independent of the current user and applications or processes in use.

• HKEY_CLASSES_ROOT (HKCR): This root key contains the file-class, OLE, and COM object data. The keys, subkeys, and data within this subtree are linked to (and identical to) those contained in the HKEY_LOCAL_MACHINE\Software\Classes\ subtree.

• HKEY_CURRENT_CONFIG (HKCC): This root key is added to make current versions of Windows compatible with older Windows 95 applications. It is derived from HKLM\System\CurrentControlSet\HardwareProfiles\Current and contains configuration settings for all currently active hardware.

• HKEY_CURRENT_USER (HKCU): This root key contains profile information for the user currently logged in. Each time a user logs on, HKCU is rebuilt with that user’s profile data from HKEY_USERS.

• HKEY_USERS (HKU): This root key contains the default profile and the profiles of all users who have logged onto the computer.

• HKEY_DYN_DATA (HKDD): This root key is found only on Windows 95/98/ME. It is linked to HKEY_LOCAL_MACHINE and contains information about Plug and Play hardware components. HKDD , for use with the Plug-&-Play features of Windows, this section will change as devices are added and removed from the system.

The “HKEY_” at the beginning of each root key’s name indicates that the key is a unique identifier (or handle) that programs can use to access resources. Each of these root keys branches out, first into keys and then further into subkeys. At the end of these branches of keys and subkeys lay the Registry data, or value entries, corresponding to the data stored in the hive files. The Windows Registry can store several different value types, but the most common that you will see are binary, strings (text for humans), and DWORD (Boolean) values.

Registry Hives

Much of the information contained in the Registry is stored on the computer’s hard drive as a set of binary data files aptly named “hives”. The hives are permanent Registry components, serving as both supporting files from which Windows retrieves Registry data during system startup, and as backup files that the Registry writes to each time its supporting data is altered or changed through a process called flushing. Flushes are automatic and occur within a few seconds after changes are made to the Registry.

How To Create A Windows XP Recovery Kit

credits : Otis Cooper

We all just love our computers, especially when we want to enjoy those high priced games and when we use it as a business tool.

But what a pain in the "you know what" when the system fail to perform as it should or worse yet, we experience a disaster with our operating system.

When you understand Windows XP, you will soon learn that there are ways to recover from a Windows XP crash.When followed in detail, there are certain tasks you can perform that will allow to recover from any Windows XP failure, no matter how serious the issue.

When troubleshooting Windows XP, there are two possibilities as to where the problem may be.This problem may be with Windows XP or it may very well be a hardware problem.In either case, the best way to recover from this is to have an XP Recovery Kit at the ready.

This kit will enable you to get your computer up and running in minutes rather than hours. This kit consists of backups of your entire hard drive.You will save yourself a heap of troubleshooting procedures that you would have to perform otherwise without this recovery kit.

To get right to the point in creating your own XP Recovery Kit, you will need disk imaging utility such as Drive Image by Powerquest and a backup medium such as a cdrom writer,a dvd writer, or a second hard drive.

There are two procedures you can perform to create an XP Recovery Kit.And these procedures can be use to create kits for other versions of Windows as well.Using a recordable medium is the first and using a second hard drive is the second method.

You also have the option of re-installing Windows XP as a form of recovery but this process takes time.Creating your XP recovery kit will require time as you make this kit but after this, you can quickly get any system running again just as if nothing went wrong.

To use cdroms or dvds, make sure your cd or dvd writer is functioning properly.Install and run Drive Image.We used Drive Image which cost $69.95 but you can also use such free or trial versions of drive imaging software.

One good software is the Back-Up 2006 by Andy Shroebel at http://www.backupmaker.com which should perform the same tasks as Drive Image.

After running your imaging software, follow instructions to create an image of Drive C. You will have the option of choosing cdrom, dvd, or second hard drive to perform the image.You will also see the number of disks required to complete the process.

The Image software should reboot the computer and perform the backup.When using disks, you will need to remove and insert the cds as needed.Label the cdroms in order and put them in a safe and secure place.

When using a second hard drive, you will know to know how to install it on the ide cable.Formatting and partitioning the second must be done before it can be used.

Windows XP have a backup utility but Windows XP home edition will have to install it from the cdrom.Place the XP cd in the drive, open My Computer, and right click the CD Drive containing the XP cd.

Now click Open and you will see the contents of the cdrom. Click the ValueAdd folder, then the MSFT folder. Next click the NTBackup folder and click NTBACKUP to install the backup utility.

But the Windows XP utility will not record to cdroms or dvds but will only save the backup as a file.This is why its best to use Drive Image or a compatible software.

After completing your drive image by backing up Windows XP on cd, dvd, or second hard drive, you will not be so concerned should Windows XP freeze up and fail to load.

Simply reboot the computer and access your BIOS to let it know which medium to boot from.Save the change and place the cdrom or dvd one in the drive and reboot.If you used a second hard drive,simply reboot and that's it.

Now don't be tempted to wait until Windows XP fail and say you should have made that recovery kit.Take the time to make an image of your hard drive and be prepared for any failure brought on by Windows XP.

The Benefits Of USB Adapters

Credits : Michael Brown

Finding an available port for your computer peripheral could be very difficult, particularly if you need several ports for your numerous devices. And the difficulty gets more challenging if what you are looking for are ports with serial, parallel and non-USB connectors, because modern computers have either reduced or removed the use non-USB ports.

If you cannot find any available non-USB ports, you can still your non-USB devices to use. Simply get yourself a USB adapter. You may ask, is a USB adapter better than the conventional expansion card? Here are the advantages of employing a USB adapter:

1. Compatibility. Whether you wish to connect the serial, parallel port, or any other non-USB ports to your computer using the USB adapter, you won't have any problem getting them to work properly. The USB adapter allows your devices to work if connected to a USB port.

2. Price. Buying an expansion card is more costly than buying a USB cable.

3. Universality. In the past, there were certain ports that were compatible with only specific devices like printers and modems, particularly for printer ports. USB Adapter accommodates all (depending on the sort of USB adapter) non-USB connectors of any computer peripherals. This short list would include joysticks, keyboards, modems, and mouse with 9- or 25-pin serial connectors.

4. Availability. USB adapters are more plentiful than expansion cards and, in turn, are easier to locate. A local computer store or online store could be a rich resource.

5. Practicality. While most of the devices on the market have USB connectors, computers and other host systems also have USB ports. And because non-USB ports are harder to find, you can resort to a USB adapter to connect your non-USB devices to your computer.

6. No extra expansion cards required. Normally, when you link devices with a non-USB connector to your computer you would need additional expansion cards for each of these. If you would add a joystick and a modem or any peripheral with non-USB connectors, you would have to add an equal number of expansion cards for each use. With a USB adapter, all you require is a USB port to link any non-USB device to your computer.

7. Multipliable. Because a single USB port can accommodate up to 127 devices (including hubs), you can attach several non-USB devices without the need of expansion cards. This means that if you have numerous non-USB devices, all you need to do is to provide each with USB adapter and a hub to connect them to the source.

8. Simple installation. If you prefer to use an expansion card for your single device, you have to open up the computer casing in order for the expansion card to be installed on your motherboard. But that is not the end of it. You still have to turn on your computer to reboot it before the card will start working. With a USB adapter, all you have to do is to attach the connector of your non-USB device to the adapter, insert the adapter into the USB port of your computer and in no time, your device is working--even while your computer is turned on.

With all these advantages, would you still prefer using expansion cards for your non-USB devices? Definitely not! The availability of USB adapters has made connecting devices to your computer quicker, cheaper, and easier.

Web Browsers – Different Types And Uses

Credits :Joe Goertz

A browser is an application that provides a way to look at and interact with all the information on the World Wide Web. Technically, a web browser uses HTTP to make requests of web servers throughout the Internet on behalf of the browser user. In other words, a web browser is a software application that allows one to view pages on the World Wide Web.

The history of the web browser can be traced back to 1991, when a computer guru named Tim Berners-Lee invented the very first web browser. It premiered on February 26, 1991, and ran on NeXSTEP. It was called WorldWideWeb, but was later renamed Nexus in an effort to avoid confusion with the World Wide Web.

There are different web browsers that are available and in use today and they all come with a variety of features. Some of the available web browsers include Amaya, AOL Explorer, Arachne, Arlington Kiosk, Avant, Camino, Dillo, Elinks, Epiphany, Flock, Galeon, iCab, Internet Explorer, Internet Explorer for Mac, K-Meleon, KioWare, Konqueror, Links, Lynx, Maxthon, Mosaic, Mozilla, Mozilla Firefox, Netscape, OmniWeb, SeaMonkey, Safari, Opera and Off By One. Most of these web browsers are free, but there are five of them that do have a purchase price.

Web browsers also come with some features. Some common features that are included with web browsers are spell checkers, search engine toolbars, download managing, password managing, bookmark managing, as well as form managing. Accessibility features that may be included with many web browsers include page zooming, ad filtering, pop-up blocking, tabbed browsing, incremental finding, HTML access keys, voice controls, mouse gestures, spatial navigation, text to speech, and caret navigation.

With so many web browsers being available, there are a number of different technologies that are supported. Some of them are frames, Java, XSLT, XForms, RSS, Atom, SVG, WML, VoiceXML, MathML, and XHTML. Also, with many web browsers, support for different languages is possible, and some of the different languages that are supported by web browsers include English, Slovak, Arabic, German, Dutch, Turkish, Swedish, Chinese, French, Spanish, Thai, Hebrew, Italian, Greek, Russian, Polish, Welsh, as well as hundreds more.

A web browser is a powerful tool, and isn’t just used for personal computers anymore; there are web browsers that can be used on mobile phones, handheld game systems, as well as pocket PC’s.

Web browsers can also be personalized to an individuals needs by utilizing web browser accessories that are not included with the initial browser software. These applications are referred to as “plug ins”, and a few of the more popular ones are Beatnik, QuickTime, RealPlayer, Shockwave, VivoActive Player, as well as Adobe Acrobat Reader.

Beatnik is utilized to receive high-quality sound and audio from websites. QuickTime, which is a product of Apple, Inc., works as a delivery system for such things as 3D animation, audio, movies, MIDI soundtracks, and virtual reality. RealPlayer delivers on demand audio and video without the hassle of waiting for downloads to complete. Shockwave allows multimedia files to be viewed directly in a web browser. VivoActive allows viewing of on demand audio and video from sites that offer VivoActive content, and Adobe Acrobat Reader allows access to PDF files on the World Wide Web.

Knowing all of the web browsers and their specific uses, it will become easy to understand how choosing the right web browser can enhance the Internet experience.

Who Else Wants To Tweak Windows XP For A Faster PC

Windows XP has lost of colours, themes and similar special effects to make your PC look great. These effects slow down your PC and that is the main problem.

If your computer is running slow, and you are sure you do not have a virus, spyware or adware you may try using some of these Win XP tweaks. The more special effects you remove the better.

Some of the effects that slow your PC are:

1. Pictures on the desktop background. A blank wallpaper is the best. Animations or even sounds in the background slow PC even more. Remove Shortcuts on the Desktop. This will be described further below as well.

Right click on My Computer icon and select properties. Go to Advanced Tab, and select Settings next to Performance. Finally select Adjust for best performance. Click OK twice. That is one of the best Win XP tweaks.

2. Is your browser by default plain, or did you install many extensions, themes and cursor symbols? Those slow down speed, so removing them is the best solution if you have a slow PC.

Switch to Windows Classic Theme by right clicking on Desktop and go to Properties.

3. Sounds also cause speed problems, so removing them is another good tweak. These include also startup and shutdown sounds. Remove sounds from your control panel. Double click on the Sounds icon.

4. A lot of MsWord, Notepad, Image and similar files scattered around on your desktop or located in shortcuts can be removed or arranged.

Create new folders, and organise your files. A folder for MsWord documents, images, sounds and Notepad files so you do not waste space.

Shortcuts on your desktop, in start menu and anywhere else can be removed to tweak XP. These are unwanted and are safe to be removed. You know if an icon is a shortcut or not because once you click delete you can read:

"Are you sure you want to delete this shortcut?"

5. Use the search tool to find unwanted files. WIn XP search tool allows you to search for certain file types. For example you can search for only images .gif or .jpg. You can find all the images on your PC, and remove all the unwanted image files.

Same with sound files, documents and you will be amazed about this stuff that has piled up during the years. A brand new computer does not need to search for these files.

Be careful though when using this tweak. Do not remove files you are not sure what their use is. Some files may be system files useful for your PC to work well.

Doing so can damage your PC.

6. Bookmarks or favorites inside your web browser have their negative side too. Same with cookies, cache and browser history.

Remove unwanted sites from your favorites. In Internet Explorer remove cache, cookies and history by selecting Tools, Internet Options and clicking the desired action.

In other browsers these options can also be tweaked from the menu which is usually under Tools. Remove these unwanted files often, or weekly. A weekly or more often job is clearing your recycle bin which helps cleaning wasted space.

Those 6 tweaks will organise your PC for a faster performance. It is the basic for XP users who suffer from slow speed. Even if your PC is not slow, some of the tweaks are still useful in the long run.
