Usually, the computer can't find the dns server, or the dns error may be due to a problem writing the address of the computer's dns server or the server is unavailable.

Tool material: windows system

1, the general problem of dns server address is that you can't open the URL, just enter the ip address directly. Turn on the start in turn->; Control panel->; Network and * * * Enjoy Center->; Local connection.

2. Select version 4 of the inter protocol, and double-click to open it. Generally, it is set to automatically obtain the dns server address. If the obtained address is unavailable or unavailable, you can manually fill in the available address, such as Baidu public ***dns 180.76.76.76, as shown in the following figure:

2. Why does the website always show that the server DNS address cannot be found?

This is because the DNS server is enabled, and the solution steps are as follows:

1. Find "Network Connection" in the control panel;

2. Right-click your default broadband connection and select Properties;

3. Click the "Network" interface card again;

4. Click "Inter Protocol (TCP/IP)", and then press "Properties";

5. Then select "Automatic Acquisition" and press "OK", that's it.

6. Explanation: DNS address is the address of domain name server, which can resolve the user's website address into IP address.

7. Method of setting DNS address:

1. Find "Run" in "Start" (or directly Win+R), and then enter "cmd" to enter the administrator operation interface;

2. Enter the command: ipconfig/all in the administrator interface, and then press Enter to confirm that the Windows IP configuration is displayed, where we can view the address of the DNS server.

3. If you are connected to the route, you can also check your DNS server address through the route. Enter the address 192. 168. 1 in the browser to open the router login dialog box. Usually, the default account password of the router is: admin (it can be modified after logging in). After logging in to Routing, we can view the DNS server address on the home page.

Once we know the DNS address, we can modify it. Click the connection icon in the lower right corner of the computer and select "Open the Internet * * * Enjoy Center". Of course, we can also enter the "Open Network and * * Enjoy Center" in the control panel through "Network and Inter".

5. After entering the "Network and * * * Enjoy Center", we will click "Local Connection" to enter the "Local Connection Status" dialog box;

6. Click the "Properties" option in the "Local Connection Status" dialog box to pop up the local connection properties dialog box;

7. Select "Inter Protocol Version 4 (ICP/iPv4)" in the local connection properties dialog box, and double-click the latter to select the following properties to enter the "Inter Protocol Version 4 (ICP/iPv4) properties dialog box", where you can change DNS settings;

8. You can change the DNS address in the "Interprotocol Version 4 Properties" dialog box, select "Use the following DNS server address", and then the DNS address becomes editable, and then fill in the DNS address that we checked before confirmation.

3. The computer prompts that the server cannot be found or DNS error. How to solve it?

DNS means domain name resolution service, also known as "domain name server". It is a computer that translates the domain name you browse online into an IP address like xxx.xxx.xxx.xx, because without an IP address, you can't connect to the Internet.

Of course, if you know the IP address of a website, you can connect by typing it directly. When DNS can't connect, you can't surf the Internet, but network services that don't need domain name resolution, such as email and online chat (using chat tools), are not affected.

Obviously, this is because the DNS settings are incorrect. The modification method is as follows: Right-click Online Neighborhood, select Properties, and then the network connection box pops up. One of them is your internal connection. The most commonly used name is: After the local connection finds him, right click and select Properties to pop up a box of network connection properties. In the middle box, find the Internet Protocol (tcp/ip), click it, and then click.

If it is set to automatically obtain IP and DNS, you must fill in the IP and DNS manually. Because DNS and other information are different in each region. I'm not sure where you should fill it out. You can only call the toll-free number of your network provider, for example, the telecom number is 10000, and ask the customer service girl how to fill it in, so that they can send someone to your home for free.

4. What should I do if I can't find the server or have a dns error?

Causes and corresponding solutions

Website failure: When you find that other websites can be opened, but this website can't be opened, it may be because the domain name server fails or the website link is deleted, or the line of the network server is accidentally blocked, resulting in users in a small number of areas unable to link.

Solution: This question is mainly about the website you want to visit. At this time, we will refresh the web page and wait for a while.

Virus intrusion: the virus in the computer may be hijacked by dns, for example, some homepages are passively or actively tampered with, resulting in some webpages not being opened or jumping to other websites.

Solution: Use the genuine antivirus software downloaded from the computer to scan the computer comprehensively to see if there is any virus. If there is no virus, you can still open the webpage after antivirus, which is probably caused by a virus.

Network failure: Network failure is a common cause of DNS errors. For example, we often get this prompt because there is no internet when browsing the web. Solution: Check whether the network is down.

Dns configuration error: Generally, you can access the Internet by automatically obtaining the dns already set in your computer, but you need to set it yourself in special circumstances. It's normal to know that the webpage cannot be opened due to dns input error, which is more common than the QQ that we often encounter but the webpage cannot be opened.

Please refer to the following steps to understand the correct dns configuration method of the computer.

Correct computer dns configuration method

Process: Start → Control Panel →→ Network and * * * Enjoy →↓

↓→ Click View Status behind the local connection → Properties →inter Protocol 4 (TCP/IPv4)→ Properties.

"Automatically get dns server address" is usually displayed, but when there is an error in dns, we need a simple setting.

Just set it up directly and try to connect to the Internet.

5. Can't find the server dns address, how to solve it?

Operation method: 0 1 First, make sure that this webpage is the only one that can't be opened. If only a single website can't be opened, it means that it is a problem of this website, as shown in the figure.

If not, let's change the DNS settings of this machine. First, right-click the small computer in the lower right corner of the desktop. Select and open "Open Network * * * Enjoy Center" 03, then click the local network connection as shown in the figure, and click with the left key.

This page is to check the network connection status, and then click Properties to enter the network card information configuration. Left-click "iPv4 Protocol → Properties" to prepare for configuring ip information in the next step.

Fill in the dns configuration information in the box shown in the figure, and click OK to solve the DNS configuration problem. Just reopen the webpage.

6. The web page cannot be displayed when the computer appears, and the server DNSadress cannot be found. What should I do?

The problem of IE browser itself

When the IE browser itself fails, it will naturally affect browsing; Or IE is maliciously modified and destroyed, which will also lead to the inability to browse the web. At this time, you can try to repair it with IE repair, or reinstall IE.

virus infection

The virus infected the application layer gateway service of XP system, which caused the webpage not to be opened. Solution:

There is a situation where you can only go to QQ but can't open the webpage. It will be fine after restarting. However, even if you restart, you can't open a webpage after opening 7 to 8 webpages, so you can only go to QQ. Sometimes telecommunications will let you disable the application management service, and it will be solved. This is because an unknown virus infects the application layer gateway service of XP system, which makes XP system users unable to open web pages. After virus infection, the service will start automatically every time the system is started, and a alg.exe process will be generated in the background. As long as the application layer gateway service is turned off manually, this problem can be solved: click the control panel-click the management tools-double-click the service icon-double-click the second application layer gateway service item-select Disable in the startup type-click Apply-click Stop-click OK-restart the operating system.

7. Computer network prompts that the server cannot be found or dns error. What should I do?

1) If it is a broadband problem, directly connect the broadband network cable for testing. If it is a broadband problem, contact broadband customer service to solve it.

2) If it's a router problem, if it worked before, it won't work for the time being. My own way is to disconnect the power of the router and plug it in. See you later. If there are any, you can restore the factory settings and start using them from the new settings (this is on the premise of correct physical connection).

If I can't solve it all the time, I suggest calling the customer service of the router. They have telephone online guidance. If I encounter problems that I can't solve, it is very useful to ask their advice. They will provide correct advice for your setup or operation. 3) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

4) If the wireless switch is off, just turn it on. If it is a software wireless connection, the software is not easy to use, and it is normal to have problems frequently. There is no better way to use a router. In addition, the network card driver is not suitable or not suitable, and there is something wrong with the network cable interface or network cable.

If you have any questions, ask me.

8. How to solve the problem that the server dns address cannot be found?

The service may be down for many reasons, such as local DNS hijacking and DNS shielding of telecom operators, which makes it impossible to find the DNS address of the server.

Usually, the computer can't find the dns server, or the dns error may be due to a problem writing the address of the computer's dns server or the server is unavailable. The solution steps are as follows:

1, the general problem of dns server address is that you can't open the URL, just enter the ip address directly. Open Start-> Control Panel-> Network and * * * Enjoy Center-> Local Connection.

2. Select version 4 of the inter protocol, and double-click to open it. Generally, it is set to automatically obtain the dns server address. If the obtained address is unavailable or unavailable, you can manually fill in the available address, such as Baidu public ***dns 180.76.76.76.
