A client is nothing but a requesting application or a user, which is trying to make some contact with the main sever. It is with the help of the network that the client manages to establish contact with the servers. The word “client” was used for the first time when it was found that some systems weren’t able to run programs all by themselves. However, the programs ran only when computers were connected through a network. Even today, the client server modules are used and this becomes more than evident when we look at the Internet since Internet uses the same concept.

With respect to the Internet, the user is able to avail the services of the World Wide Web simply through an IP suite. In this case, the web browsers are nothing but the clients which simply connect to the web servers and display the respective pages to the user. When the users want to retrieve their e-mails, they use the e-mail clients from the ISP’s storage servers. These clients always vary according to the applications they are used for. For instance, the clients used for online chats usually depends on what kind of chat protocol is being used. And with respect to online games, well, game clients are usually used for multi player online games.

There has been a change off lately in the sense that client programs are tagged along with websites, which makes the browsers act like universal clients making the entire process easy for the users. This is achieved due to the fact that instead of communicating with separate servers all the time, it is easier to connect through a browser and this is clear from the advancement of web mail. There are three types of clients, they are, Fat Clients, Hybrid Clients and of course, Thin Clients. The fat client is mostly used by users for their personal computers since they are known to operate solo. On the other hand, the thin client uses other resources and all it does is just display the images from the server. And then of course you have the hybrid client which is a combo of the above two client types. This way, the hybrid clients offer enhanced performance, multimedia compatibility and flexibility.

Microsoftupdate.com is one of the many official websites hosted by Microsoft Corporation. Its basic purpose is to provide updates for Microsoft products such as Windows Operating System, Microsoft Office Works and many others. Since the update needs vary from user to user, microsoftupdate.com uses Active X controls to determine the exact version that’s running on a particular computer and also the updates that it requires. When this is done, the required updates are automatically downloaded and installed on the system.

Some experts are of the opinion that since updates from microsoftupdate.com slows down the system, users should avoid it completely. However, I don’t agree with them because I believe that a slightly slower system is a small price to pay for protecting your computer against all types of emerging security vulnerabilities. A significant percentage of updates are meant for fixing security vulnerabilities and if you don’t have them on your system, it would mean that your computer will always remain susceptible to security braches and third party unauthorized entries.

The most downloaded updates from the site relate to the Windows Operating Systems such as Windows 98, 2000, ME, XP service pack 2. Currently most update requests come from XP users. Keeping this in mind, Microsoft has plans to introduce XP service pack 3 that will contain most of the updates that have been released since XP service pack 2. It will also have many new updates, developed mainly for fixing newer security vulnerabilities and protecting your computer from newer forms of viruses, Trojans, worms, and other types of malicious software codes.

For downloading and installing Windows XP updates from microsoftupdate.com, you just have to enable the “automatic update” option from the control panel. You can also directly visit the website for achieving the same. If you face any problems, you can contact customer care either through phone support or email support. You can also access Microsoft’s huge knowledge base for finding the right answers to your problems and issues.

The use of ActiveX controls are essential for Microsoft Internet Explorer to operate effectively. Without them, certain parts of a web page may not function in the way that the designer intended.

ActiveX is an umbrella term for a loose set of Microsoft technologies. They cover a wide variety of purposes, but the most common includes the ability of OLE to integrate with Microsoft’s popular browser. ActiveX controls are responsible for translating data in to a visual representation on the screen. For example, you might use an ActiveX control to access an embedded spreadsheet. Another popular use comes in the form of an integrated FTP window.

For all of its technology advances, ActiveX is actually quite unstable if left to work on all websites. Malicious users have found a way to target browsers with weak security, and they’ll go as far as to distribute spyware through the misleading certificates of the control.

Many ActiveX errors are triggered by browsers that have had their security settings tampered with. If the security levels aren’t adjusted to accept ActiveX controls, the additional content won’t function and you’ll be left with an error. This is a very common problem and thankfully it’s easy to fix.

Presuming that you’re running Microsoft Internet Explorer, follow these simple steps;

• Select Tools > Internet Options from the top toolbar.
• Navigate your way to the Security tab and notice the different levels. Set the security bar to Medium.
• Click on the Custom Level tab. Ensure that the following boxes are checked; “Run ActiveX controls and plug-ins”, “Script ActiveX controls marked safe for scripting”, and “Scripting”.
• Save and apply your changes.
• Relaunch Microsoft Internet Explorer

This should ensure that ActiveX controls display properly in your browser.

It’s possible that you may still receive an “ActiveX disabled” error. If this is the case, it’s likely that the problem stems from an anti-virus program. Many of these come with settings which disable scripting from the browser, and they will override the existing Internet Options. If you are still having difficulty getting ActiveX to display, ensure that scripting is enabled on your anti-Virus program. There’s an easy way to test whether this is the source of the problem.

Try disabling your anti-Virus protection and refresh the page. If the ActiveX control displays, you know for sure that it’s the anti-Virus suite that is causing the clash. Of course, these programs can be configured very differently. We’d recommend that you check the support site for your software and locate the correct configuration settings. Alternatively, find a “Restore Default Settings” option in the suite and click this. Be careful though, this will return ALL settings to the default values.

Don’t rule out the possibility that an ActiveX control is simply not coded correctly. They aren’t the simplest plug-ins to work with and if a developer uploads code with a slight fault, the entire control will return an error. It may seem as if your browser is to blame, but it’s actually the fault of the coder. Check for a test ActiveX control from Microsoft if you’re unsure.

It’s unlikely, but ActiveX errors can also be triggered by a deep routed problem with the system video card and its drivers. You will typically see a lot more problems than mere ActiveX errors alone if this is the case, but it shouldn’t be ruled out completely. It’s a good idea to keep your video drivers up to date as a matter of good habit. You can upgrade them from the system settings.

If this still doesn’t fix the Active X control, it’s worth visiting the DirectX website and downloading the latest components for your machine. Once again, it’s highly unlikely that a graphics card fault will be the real source of the problem. If it is, you’ll typically notice the performance setbacks in everything that your system does.

ActiveX isn’t the most stable of technologies and its controls can be easily affected by the settings of a browser of the configuration of an anti-Virus package. Be sure to check that scripting is enabled, and if this doesn’t do the trick, consider upgrading your video drivers and obtain the latest DirectX software.

ActiveX is a series of strategic object-oriented programming technologies and tools that were introduced by Microsoft in the late 1990s. The ActiveX name is not used very often today and most of the technologies that used ActiveX are considered defunct or have been renamed. However, some of the ActiveX technologies are still used widely. People like to view dynamic and exciting web sites and this is where ActiveX controls come in.

ActiveX security is somewhat of a concern because it relies entirely on the judgment of the computer user. An ActiveX control will have a digital signature from the developer of the program and other parties that choose to endorse the program. Once the internet browser has verified the digital signature on an ActiveX control, it will provide you with a window that will give you information about who has signed the application and will ask you whether or not you want to trust the signer. Because of this, ActiveX relies entirely on the computer user to make the right decisions about what software should and should not be run on your computer. If a poor judgment is made, malicious software may be allowed to run on your computer system causing many headaches.
