What s the reason for the wrong name of the dsn?

DNS server-side issues. A common solution is to customize another DNS server.

Search for one based on your location.

I don't know if the following can be used.

If there is a virus in the computer, it may be malware that tampers with the user's homepage and hijacks the DNS.

Solution: Antivirus software to check whether the computer is virus-proof.

If. Fault, if it's just a DNS error and something else is open, it's likely that the nameserver is faulty or the server is faulty.

The DNS settings of the computer are incorrect.

Most friends use automatic DNS to access the Internet, but many LANs need fixed IP, choose a fixed IP address, you need to enter DNS, DNS input error will cause the web page to not open.

1. First select the computer or my computer and this computer on the desktop of the computer and right-click the mouse to select the device manager, 2. Select the network adapter, 3. Select the realtek driver in the network adapter and double-click to open, 4. After opening the properties window, switch from the current general tab to the power management option, 5. It will allow the computer to turn off this device to save power Check Cancel and OK, 6. Then you can solve the problem and surf the Internet normally.

You just change the DNS to OK.

To do this, right-click on the network icon in the bottom right corner of Network & Sharing Center Change adapter settings on the left Select the NIC you want to change DNS, local or wireless Right-click properties Internet Protocol IPv4 Preferred DNS Enter Save Exit.

Set it to get it automatically, or check the DNS of the network (mobile, telcom, etc.) in your area. What system?

You change to a DNS. Common, such as 141DNS: Preferred standby.

Google DNS: Preferred Alternate.

Routing issues. Route self-test.

Analyze if there is a problem with the space.

Analyze whether there is a problem with the domain name provider.

Check the space for viruses.

Analyze whether the domain name is set incorrectly. Since many of the current domain name resolution services are set up by domain name providers, of course, some users need to change some options during the operation, resulting in the failure of domain name resolution. If you can't open it, then you need to analyze it through the software, and after finding that it is a domain name resolution problem, you can log in to the corresponding background provided by the domain name provider, select the corresponding options, fill in the relevant parameters, and under normal circumstances, if you don't know how to parse, it's actually very simple, just ask the customer service staff of the business to parse.

Analyze if there is a problem with the space. If you log in to the background of the domain name ** business and find that there is no problem with the A record related to the domain name resolution, the MX priority and the host record pointing, and the domain name has also been recorded, at this time, if the domain name is still not opened, and the domain name resolution error is displayed, in fact, it is not the problem of the domain name resolution, but the problem of the **space, that is, the **space can not be connected to the Internet, and the corresponding domain name and the IP address of the virtual space can not achieve a one-to-one correspondence relationship, from the point of view of the wrong manifestation, A domain name resolution error is also displayed. Therefore, at this time, it is necessary to analyze the quality of the space, and if the space is unstable, then it needs to be replaced in time, or the IDC provider is required to improve it as soon as possible.

Analyze whether there is a problem with the domain name provider. Nowadays, we need to register domain names through domain name registrars, and these registrars usually have their own servers to handle domain name resolution. Moreover, this name server is generally a dual-machine hot standby server, and keeps running normally 24 hours a day, but once the server is down or the domain name A record and host record and other information are changed, only wait for the server to restart, or the server will come with the domain name information refresh function, generally between one hour and two hours, it will be refreshed, and the domain name record table will be updated, so that the modified domain name or damaged domain name resolution can be restored.

Check whether there is a virus in the ** space, which interferes with the domain name resolution. DNS hijacking is a key factor in the current domain name resolution errors. Domain name hijacking is on the server side on the one hand, and on the client side on the other hand, for webmaster friends, it is necessary to solve the problem of virus infringement on the server side.

That is to say, the domain name of the server where the **space is located has been invaded by a hijacking virus Trojan, which makes it difficult for the **space to be parsed correctly. Therefore, at this time, it is necessary to increase the virus detection and killing efforts in the server space and improve the security of the server space, only in this way can the problem of domain name resolution be effectively solved.

Note, you can also contact the access provider to see if it can be solved.

First of all, let's explain what a domain name is: Usually these addresses we visit are called domain names, but the hosts in the network are identified by IP addresses, so only if you know the IP address of ** can you access and other operations normally.

If a domain name resolution error (**105) occurs when opening a web page, it means that there is an error in the resolution process between the IP address and the site, and you need to configure the DNS server and IP address on your mobile phone.

Tools Raw materials.

Computer. 1. Check whether the DNS is really faulty.

1. Open the cmd command line window and press enter nslookup to confirm.

2. The above figure will show the DNS server address used by the current system.

3Enter the domain name of a site you are familiar with, e.g., if it appears.

dns request timed out，timeout was 2 seconds

This indicates that the DNS system is faulty.

End 2: How to Solve DNS Faults.

Find "Start" - Run "- Enter cmd" to open the command line window.

Run the ipconfig all command to query the network parameters.

In the image above, we can see the DNS server address.

In the same way, you can check the DNS servers of other users who can access the Internet in the same LAN. Just change your own to someone else's.

If you only change the DNS server and cannot access the Internet normally, you need to manually configure the IP address and change the last segment of the IP address to be different from others.

There are generally two reasons for the occurrence of DNS domain name resolution errors: 1. Your local network is wrong, check whether your computer can be opened 2. Your regional DNS problem, change your network DNS address 3, **server error, or**domain name error (this one is very likely and is frequent).

If the security guard is installed, you can directly use its disconnected first aid kit.

If it is not installed, click on the Neighbor properties and disable it in Enable.

Submit your space provider, and so do the space I use in vhostfull abroad.

The possible reasons for a domain name resolution error are: 1) The domain name expires.

2) The current signal is not good.

3) Connected maliciously.

4) Expiration.

5) Parsing error, not connected to **.

If the resolution is wrong, go to domain name management to see the resolution status!

Go to your ** space background to configure, if you don't understand, you can find your space service provider and consult how to change it.

Failure to resolve the server's DNS address may be due to a problem with the router and the inability to assign an IP address; The DNS settings of the computer are incorrect; The computer did not get the DNS.

Workaround for DNS resolution error:

1. Clear the DNS cache, open [Start], click [Run], and enter [cmd] in the run

2. Enter [cmd] and click to confirm, after the pop-up window, enter [ipconfig flushdns] in the window

3. After entering, press Enter, and [DNS resolution cache has been successfully refreshed] appears, which means that the DNS cache has been successfully emptied.

4. The next step is to set up DNS, open [Control Panel], find [Network & Internet] [Network Connection], select [Local Connection], and right-click to enter [Properties].

5. After entering, select [Internet Protocol Version 4] and double-click to enter.

6. After entering, select [Automatically obtain IP address (0)] and [Automatically obtain DNS server address (D)], and then click confirm to complete the setting, and then you can connect to the Internet normally.

This has something to do with your local broadband cache. Generally not yours is the problem. It's a problem with your broadband.

The DNS server to which your broadband belongs does not update the DNS records of the domain name in a timely manner, resulting in invalid access to the domain name, or the DNS server of the broadband is unstable, so it is sometimes good and sometimes bad.

You can "Start" > Run > cmd > enter ipconfig flushdns > enter.

Refresh the cache and try again.

When you can't access it, you can ping whether the domain name resolution is normal, as you said, the resolution should be abnormal, if not, contact the domain name provider directly.

Hello, for your problem, there are many reasons for domain name resolution errors, and I hope to refer to it.

1. For example, it is difficult to resolve the domain name due to the space factor.

2. The domain name resolution error caused by the server failure of the domain name ** provider.

3. Also, because the ** setting error will also lead to the failure of domain name resolution.

4. In addition, there is also the problem that ** is attacked by viruses, which will also lead to the problem that the domain name is difficult to resolve.

Generally, this error indicates that there is a problem with the server you are accessing.

Check that your network is working.

It's also possible that your service provider is wrong.

If the DNS address is resubmitted, the DNS system will update the DNS address to the new address within two hours.
