Dns Server Not Available?
There are situations when computer users are faced with the fact that the Internet does not work for them.
One of the most common reasons why this happens is the error “DNS server is not responding.”
Inexperienced people immediately panic, but this is not worth doing. The article will describe in detail the problem and suggest ways to solve it.
This is a specially developed tool that redirects requests from a client or computer from a client to the Internet domain of interest.
When accessed by the user to any page in the “global network,” he gets access to a particular remote server, or rather, to one of its sections containing the necessary data.
or easy viewing and scaling, they are converted to a text view using the built-in browser mechanisms.
Any remote server, regardless of its subject matter or place of registration, has a specific IP address. When sending a request from a computer, the client accesses this address.
Sometimes there is a situation when the browser does not display the necessary information. This is the required “DNS-server does not respond,” and the error in question is displayed on the screen.
The most common failure of the DNS server is due to the fact that the error occurred with the service provider.
Inexperienced users should not panic and take rash actions that could aggravate the situation and lead to the formation of additional problems.
The only right decision would be to find the phone support service indicated on the pages of the concluded contract for the supply of Internet services and contact a specialist.
After that, the wizard will ask you to name the data needed to determine the cause of problems with the DNS server:
- the first name, last name of the subscriber;
- number of the concluded agreement;
- time of occurrence of failures, etc.
If the problem is technical and is on the side of the Internet service provider, the representative of the provider will report this, indicating the approximate time frame for rectifying the situation.
In general, technical specialists are competent people; in any case, they will advise what to do next.
Checking the service “DNS client.”
If the provider is “not guilty” and the device or a specific resource gives an error: the “DNS server” is not responding, a special service will be checked that is responsible for the correct operation of the DNS server.
In all operating systems from Microsoft to find it is not difficult. Windows 7 contains it in the “Services” section.
- To do this, after right-clicking on the “My Computer” shortcut, select the “Management” sub-item.
- The window that opens shows the “Services” section, click on it, find the desired user, which has the word DNS in the title.
- Then right-click to select the type of startup “Automatic.”
- Then, for security, select the “Restore” tab, where the service is restarted when problems occur.
- Windows 10 contains a service tab in the Task Manager.
Ways to fix the error
The problem in which the remote server cannot be contacted due to DNS problems arises either on one Internet resource or when trying to connect to the global network simply. Many users are interested in how to quickly fix a DNS error.
The problem is solved in different ways, the main thing that is being done to correct the situation successfully is to determine the reason why the DNS server crashed on the Windows server.
Change DNS server settings
The first way, when DNS fails, is to change the current settings of the DNS server. The easiest way to install servers is Google, the largest Internet company in the world.
They are guaranteed to work, a situation in which you can not find the DNS is excluded.
- Next, you need to go to the “Network Control Center.”
- To do this, simply click on “Start”, then find “Control Panel,” go there, select the desired item.
- You can also right-click on the wifi icon on the bottom right of the screen, select the desired item.
- Identify the section where the adapter settings change.
- Find an existing internet connection.
- In its settings tick is removed, which is responsible for automatically obtaining the addresses of the DNS server. Fill in the empty fields with the addresses provided by Google: 184.108.40.206 and 220.127.116.11.
Clearing DNS cache
Another way to fix a DNS server error is to clear the cache. The easiest way to do this is via the command line.
- Opened with the help of the clamped two keys Windows and R.
- Then the field is filled with the value of cmd, and the OK button is pressed.
- Several commands ipconfig / flushdns, ipconfig / registerdns, ipconfig / release , ipconfig / renew are entered.
- After that, restart the computer.
According to the results of the manipulations, there should be no problems with the DNS server.
Antivirus blocked DNS
In some cases, DNS failure is caused by the fact that Anti-Virus installed on a laptop or computer blocks the ability to access DNS. This happens for several reasons.
Sometimes the computer is infected with a virus that blocks the ability of the DNS to work, but most often the antivirus software is incorrectly configured.
It can “not allow” to a certain resource or even completely block DNS in the operating system. Antivirus is disabled for 10 minutes.
At this time, you need to go to the browser and try to go to any site. If everything is successful, then you should look for an error in the settings of other parameters of the security software.
Sometimes the cause is a firewall. And it blocks the pre-installed firewall of the operating system or the one that is built into the Anti-Virus.
To check it is enough to disable it by analogy with Anti-Virus temporarily. This is done in the “Control Panel” in the “Security” section.
In some companies and organizations, firewalls, antiviruses, and networks are set up by system administrators in such a way as to prevent employees from visiting foreign sites.
These include social networks, torrent trackers and other types of online entertainment resources that distract from work.
This is done including the blocking of the DNS server. To solve the problem, use portable programs for configuration and anonymizers.
Updating network card drivers
The DNS server in Windows 10 often does not work. This is the newest system, sometimes causing errors due to the use of old drivers installed for the network card.
Solve the problem simply through specialized applications like Driver Booster. It is enough to download it from the official site, install as prompted and run.
After that, the program will find problem spots, redirect the user to download drivers from the “global network,” help to install them.
However, it is easy to do it in the usual ways, pre-installed in the operating system. To do this, open the “Device Manager,” find the “Network Card.” Find out the name, download the driver you need, and then click “Update.”
The most common problems with DNS servers are problems that occur on the router. In order to determine what “is to blame” for him, a computer or laptop is connected directly to the cable, which is led to the apartment by an Internet service provider.
If everything works, the DNS server is blocked by the router. The easiest way to solve the problems triggered by the router is to reset the settings to the factory settings.
Depending on the model and manufacturer, this is done in different ways. Sometimes it is enough to hold the WPS / RESET button or insert something like a needle into a special hole.
If desired, the router is configured from the inside, for which you need to go to 192.168.1.1 and solve the problem in the administrator interface.
When nothing helped
If none of the above methods corrected the situation, still highlighting the DNS error, nothing else remains but to call a specialist.
The easiest way to do this is by contacting a company with which the user has an agreement for the supply of Internet services. A master will come from the provider, who for a fee will set up and fix the problems that have arisen.
When an error is displayed on the computer stating that the DNS server is not responding, there is no reason to panic. There are many reasons leading to a crash and decisions on how to fix it.
