How to reset the DNS cache on Windows. Clearing the DNS cache on a Windows computer How to delete all time files using an additional program

Most Internet users can access their favorite resources from their home or office computer. Once synchronized, you can print your reading on your computer and continue reading it at home. Have you ever come across the fact that on one computer the site works wonderfully, all pages are accessible and can be opened in a practical manner, whereas on another computer you cannot connect to the server? As you read this article, you began to sing and sing.

Thus, the problem is often blamed on the Internet service provider. Especially since this is a local company, and not a federal giant, which has representation in all regions of the country. It is important to note that your client's DNS servers are not working correctly, and the problem reappears when you change the server address in the configured network map of the computer or in the router, the problem is clearly internal. I was caused by an incorrect DNS cache.

How to clear DNS cache? How does it function and why are there problems with accessing other sites? Find out more about our nutrition in today's material. It is important to read the instructions if you encounter a similar situation.

To explain in even simpler words, the DNS is a kind of recorder or database of all existing sites on the Internet. When you enter the name of a site in the address bar of your browser, the computer converts this address into a digital format, which consists of 4 groups of numbers separated by dots. Setting up a DNS server - as quickly as possible, set the original letter of the address to a numeric one. The larger the provider and the faster the technical support, the shorter and more functional the DNS server.

The closer the DNS distribution is geographically to your computer, the sooner you will be connected to the required side. In fact, any provider recommends using a public server instead of a public one, such as Yandex or Google DNS. To speed up the work, the computer caches information about all websites and saves it in the Windows system partition. This cache is stored both on the operator’s server and on the local computer. Because the site functions differently on different computers, it is necessary to clear the DNS cache on the problematic computer.

There are many ways to clear the DNS cache. Let's take a closer look at their skins.

Clear DNS cache

Through the command row

And even more simply and at the same time practically in the most reliable way. To clear the DNS cache on a computer running Windows 10, you need to run the Windows Command Prompt as an administrator and run a number of commands.

Depending on the version of Windows, the command line can be written like this:

• Windows 10. Right-click the mouse or press the Win + X key combination, then select the “Command Row (Administrator)” row.
• Windows 8-8.1. Press the Win + R buttons, type cmd and press Enter.
• Windows 7. Similar to Windows 8, press the combination Win + R, then search cmd in the window and press the Enter key.

Each command must be followed through, and its entry can be confirmed with the Enter key. After completing the procedure, restart your computer. Clearing the DNS cache on your Windows 7 PC may resolve problems with certain web resources being unavailable.

The way to restart the DNS client

To use the DNS cache, a special Windows service is used. It can be used through a special menu using a computer. Regardless of the version of the operating system, you can use one of the following methods:

To clear the cache, you need to find the “DNS Client” service, click on its end once, and then click the “Restart” button in the left column. After that, restart Windows and try logging into the site again. Everything can be done like a good old man.

The problem with accessing certain web resources through an incorrectly functioning DNS cache on your computer is very simple and straightforward. If you quickly follow our instructions, you can get rid of difficulties in just a few minutes. If you notice that your computer often does not allow you to access certain sites, you will need to clear your cache regularly. In the comments, we ask you to write which of the two solution options helped you.

The intermediate results of robotic programs can be saved here so that they can be discarded. The most important things are to be stored in the RAM, the signals are quickly lost in the program cycle wheel and are used for further development. The RAM is limited, it is not enough, and it needs to be cleaned again. And some of the information that is no longer needed in the future is saved in files and saved on the computer’s hard drive. Such files are called time files. The stench accumulates, takes up space, and they need to be removed so that they do not interfere with computer work. So what are the best ways to clear the cache in Windows 7?

What is computer cache memory?

The cache memory saves the most important time-sensitive files that may be needed in the near future. For example, when you watch a video on the Internet, it will gradually be downloaded and stored in your browser's cache until you finish. Then the video is deleted due to unnecessary use. So, in essence, when you turn on a movie on the Internet, you still download it to your computer and delete it after watching it again.

Cache memory is vicorized in Windows. Make sure the results of the calculation program are saved there. Cause the cache to be deleted on time, otherwise it will accumulate and corrupt the system, so that the computer cannot determine whether the information is needed or no longer available. There are some cache memories that require regular cleaning.

How to clear your cache memory?

DNS (DPR)

DNS (Domain Name System, literally – domain name system) is a kind of address book for the Internet. On the right, the computer cannot find the required server using symbolic addresses (such as yandex.ru), before which one can be launched. The computer does not have an IP address. DNS servers, of which there are quite a few, retain their identity by IP letter address. The user, by entering a query into the search system or the address bar, sends a signal to the DNS server to find a private IP address and forces its computer to connect to the web site.

The DNS cache can be cleared using the command line. To open it, press Win + R (Windows program) and enter cmd in the field. Or open “Start”, go to the “Standard” section and launch the command row.

In the command line enter ipconfig /flushdns

The row “Successfully cleared the DNS recognition cache” will appear. DNS cache clears.

Enter ipconfig/flushdns

Thumbnail

The Thumbnail cache can be cleared using the standard Disk Cleanup utility. To launch it, open “Control Panel” -> “System and Security” -> “Administration” -> “Disk Cleanup”.

In the program, select the disk that needs cleaning. To view Thumbnails, select the system drive (name C:\). Then check the boxes next to the files that you need to delete (find the Thumbnails item in the list to delete thumbnails). Click the “OK” button and check the current hour. Thumbnail cache of clears.

Select “Thumbnail” to view Thumbnail cache

Windows has the ability to turn on the thumbnail cache, so that the icons will not be saved in memory and will become obsolete, thereby saving you valuable space in the cache memory.

Open the “Customer Panel”, in the “Design and Personalization” section, select “Folder Powers” ​​(or “Folder Options”). The "View" tab will have more options. Find the middle item “Do not cache sketches” and check the box.

Check the box “Do not cache sketches”

Nuances for RAM

It’s important to clear RAM cache fragments regularly to make the process easier. Let's create a shortcut that will help us get to the program that clears time files. Now, right-click on a free place on the desktop and select “Create” in the menu, then “Shortcut”. Now find out about the capacity of your system version (open “Computer”, right-click on the open space, select “System Power”, and there it will be indicated: 32 or 64-bit system).

Enter the row depending on the bit capacity of your OS

Be sure to enter one of the following rows in the field according to your version:

• For a 32-bit system: %windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks
• For 64-bit: %windir%\SysWOW64\rundll32.exe advapi32.dll,ProcessIdleTasks

Click “Day”, name the shortcut at your discretion and save it. Now, when you launch this shortcut, the system will analyze the software processes and see the part of the RAM that is not being corrupted. In the future, regular cleaning will help improve your computer's speed code.

How can I delete all clock files using an additional program?

To avoid messing with the skin type of cache memory, use special programs to speed things up. Advanced butt – CCleaner.

Get them from the official website. CCleaner has a simple, zipless version that is sufficient for basic operations. Purchasing the paid version here is more likely to be a donation to retailers, rather than a real need.

In the Programs window, select the “Cleansing” section. Check all the boxes that need to be cleaned. Click “Analysis” so that the program looks around the computer and identifies all unnecessary items, including caches that are not being analyzed. Now click “Clean”, and through a small number of programs, see all the software that has been found. You can also clear the cache and time files that are not corrupted, the clipboard, memory dumps, search logs, browser cookies, addresses, browsing logs, index.dat files, and much more. And if you open the “Registry” tab, you can clean the Windows registry so that it appears safely on the system’s speed code.

Click "Analyze" and then "Clean"

Possible problems

Files in cache memory are not visible

Since the program directly downloads the vikory clock files from cache memory, you cannot delete them. Make sure you are notified of those files that are being vicorized by such a program. Open the task manager, stop the process that contains the vikory file, and then clear the cache memory.

Browser cache is not visible

The browser cache can also become corrupted, so when you try to delete time files, it crashes or the browser freezes. Try closing all tabs and restarting the browser. Pardons are looming. At the very least, you can try reinstalling the browser.

Now, we learned how to clear the cache in the Windows 7 operating system. Permanent clearing will require timely DNS files, images and icons, RAM cache and browser cache. Once in a while, the files accumulate in the cache memory of all programs. However, most of them are of insignificant size and do not greatly impact the system. If you want to clear absolutely everything, use programs like CCleaner to get rid of unnecessary files and other system stuff.

If you encounter problems with the Internet connection, you need to clear the DNS. Well, today we’ll figure out how to clear the DNS cache using our own hands.
This is especially true for us if the error ERR_NAME_NOT_RESOLVED is at fault. In general, this may be needed when changing the address of DNS servers on Windows 10, 8 or Windows 7, as well as cache connections between site addresses in “human format” and their actual IP address on the Internet i). For example, like this: IP addresses - website

The simplest way

A simple method of dumping the DNS cache is still standard, but not entirely practical for the new generation of back-end users. Why? On the right is that you need to launch the command row and enter a number of commands.
Launch the command line as administrator (right mouse button will display the item “Run as administrator”). With the right mouse button you need to click on the “Command Row” program, which is located in the list of all programs (if you use Start, search through Start).

• Type ipconfig /flushdns and press Enter.


• It will display: “The DNS cache has been cleared successfully.” It all went OK.


• In Windows 7, you can also quit and restart the DNS client service. In that same command row, enter (sequentially) the following commands:

net stop dnscache
net start dnscache

How to clear your browser's DNS cache

Now, to clear the DNS cache in your browser, you need to insert one of the following commands into the address bar (depending on your browser):

• chrome://net-internals/#dns - for Google Chrome


• browser://net-internals/#dns - for Yandex Browser


• opera://net-internals/#dns - for Opera

A special page will open, which is the interface for managing the DNS cache. Here you can look through, save your entries and clear them. Just click on the button with your teeth: “Clear host cache”.
If you have problems with connections in a specific browser, then select Clearing Sockets. This can be obtained from the Sockets section (Flush socket pools button).

The repository of intermediate information on a computer running the Windows operating system is called a cache. Data is stored there that may at any time be needed to carry out basic operations on the processor, Windows or any other application. Due to the rapid access to cache memory, the most popular information is increasingly sought after, and as a result, the overall productivity of the computer increases. Fakhivtsi work hard to clear the cache every hour. Let's figure out what we need to do to clear the cache memory.

What is the cache in Windows 7

Cache (and also cache and cache memory) in a computer is called a high-speed intermediate buffer that saves information that may be needed with great reliability. In other words, there is a part of the memory (either on the RAM or on the hard disk) with high speed of read and write operations for saving information, which is often needed by the computer.

The cache contains the results of system calculations. For example, DNS (Domain Name Service) maps the text name of the site to its digital IP address on a network that is stored in a power cache. If the site has not moved to a different physical address, the DNS cache will save traffic during the attack on the server. However, in another case, the screen will display outdated information or notifications about the cancellation, which does not indicate effectiveness.

Web browsers also actively exploit this technology, automatically saving copies of pages in the buffer memory. On the one hand, it is important to save both traffic and increased traffic to the site during the next update, but on the other hand, show the pages from the previous session instead, so as not to display changes.

Windows 7 caches a wide variety of information. For example, for a quick display of pictures, they are stored in the thumbnails cache, and their thumbnails are saved there in a changed appearance (icons or labels). It is clear that with active work with graphic information, the use of buffer memory becomes great.

The need to clear the cache is due to the need to delete collected information for several reasons:

Hand cleaning

You can tamper with your operating system to clear your computer's cache memory.

DNS (DPR)

The DNS cache can be cleaned using the command line, for which there are a number of ways.

When working on the Internet - when trying to access any web pages - there are often various “overlays” - for information Server not found. It is impossible to display the side before it appears - instead of a web site - some kind of gobbledygook. Of course, most of these problems are caused by time-consuming problems with the provider’s server or website hoster.

However, most often in such cases, it helps to clear the DNS recognition cache with the command ipconfig /flushdns.

For whom:
- Press Start -> Viconti... -> Run programs -> cmd -> OK;
– switch (optional) the keyboard layout to EN;
– after the system has requested C:\Documents and Settings\Im'ya_koristuvach> enter ipconfig /flushdns, press Enter;
– the DNS recognition cache will be cleared:
C:\Documents and Settings\Administrator>ipconfig /flushdns
Setting up the IP protocol for Windows
The DNS recognition cache was successfully cleared.
C:\Documents and Settings\Administrator>

Notes
1. DNS(Domain Name System) is a system that establishes a relationship between numeric IP addresses and text names, for example, when you type them into the address bar of your browser google.ru, and DNS “translate” the address to 216.239.59.104 .

2. To successfully flush the DNS resolver cache, the service is responsible DNS client(Dnscache).
This service resolves DNS names to addresses for your computer and places them in a cache. If the service is disabled, it will not be possible to resolve DNS names and host the Active Directory directory service on domain controllers. If this service is not allowed, you will not be able to start any services that are obviously unused.
Launch type (after installation) – Auto.
The file is created - C: WINDOWS System32 svchost.exe -k NetworkService.

If the Dnscache service is not enabled, you will receive notifications when you try to clear the DNS resolver cache. Can't clear the DNS recognition cache: Disabling the Windows function.

3. How to disable the DNS client service:
- Press Start -> Settings -> Control Panel -> Administration -> Services;
- At the window that has opened Services on the list Services (local) see the DNS client service;
- Click Start the service.

4. How to set the startup type for the DNS client service – Auto:
- Press Start -> Settings -> Control Panel -> Administration -> Services;
- At the window that has opened Services on the list Services (local) see the DNS client service;
– press the left mouse button to open the window DNS client (local computer) – Vlastivosti(or click the right mouse button to select the context menu from which to select Powerful);
– on deposit Zagalni in the list that doesn't appear Launch type Select Auto –> OK;
