There are many people who can't find the server or DNS error, and then can't surf the Internet. What's the matter? So when you encounter win7 can't find the server or DNS error, what should you do? If you don't know, please take a look at the following solutions I sorted out!
Win7 cannot find a solution to the server or DNS error
Method / step:
1. Website failure: when you find that other websites can be opened and this website alone cannot 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 the inability of users in a small number of regions to link.
Solution: this problem is mainly the problem of the website you want to visit. At this time, let's refresh the page and wait a little longer.
2. Virus intrusion: if there is a virus in the computer, it may be hijacked by DNS. For example, some home pages have been tampered with passively or actively, resulting in some web pages unable to open or jumping to other websites.
Solution: use the genuine anti-virus software downloaded from your computer to scan your computer to see if there is a virus. If there is no virus, you can open the web page again after anti-virus. It is likely caused by the virus.
3. Network failure: network failure is the cause of DNS errors that we often encounter. For example, we often appear such prompts because we don't have a network when browsing the web.
Solution: check whether the network is broken.
4. DNS configuration error: generally, DNS is automatically obtained by using the one set in the computer, but it still needs to be set by yourself in special circumstances. It is normal to know that the web page cannot be opened due to DNS input error. We often encounter QQ, but the web page cannot be opened. At this time, we have to configure DNS correctly. See the following for specific methods:
(1) start → control panel → network and sharing center.
(2) click change adapter settings → right click local connection and select Properties → Internet Protocol 4 (TCP / IPv4) properties.
(3) generally, "automatically obtain DNS server address" is displayed, but if there is an error in DNS, we need to simply set it.
(4) just set it directly and try to connect to the offline network.
Supplement: server introduction
Servers, also known as servers, are devices that provide computing services. Since the server needs to respond to service requests and process them, generally speaking, the server should have the ability to undertake services and ensure services.
The composition of the server includes processor, hard disk, memory, system bus, etc., which is similar to the general computer architecture. However, due to the need to provide highly reliable services, it requires high processing capacity, stability, reliability, security, scalability, manageability and so on.
In the network environment, according to the different types of services provided by the server, it is divided into file server, database server, application server, web server, etc.

1. System blue screen, frequent crash, restart, slow response
The of the server is very similar to our ordinary computer, whether it is hardware structure or running system. Therefore, just like our computers, they may be infected with viruses, crash, blue screen, restart and other failures due to system vulnerabilities, software conflicts and hardware failures, and slow response due to too much garbage cache information.
2. The remote desktop connection exceeds the maximum number of connections
Since the server allows 2 connections by default, if you forget to log off after logging in and directly close the remote desktop, the server recognizes that the login is still on the server side. In this case, the most common is to restart the server. However, if it is the peak period, the loss caused by restarting the server is obvious. At this time, you can use the mstsc / console command to forcibly log in. Open the "run" box and type "mstsc / V: xxx.xxx.xxx.xxx (server IP) / console" to forcibly log in to the remote desktop.
3. How to clean up files that cannot be deleted
In this case, it may be that the file is still running. You can restart and delete it, or run CMD, enter the name of the folder arrtib-a-s-h-r you want to delete, and finally enter the name of the folder del wants to delete. It cannot be recovered after running this command. Please use it with caution.
4. Hidden trouble of system port
For the server, the first thing is to ensure stability and security. Therefore, we only need to ensure the most basic functions of the server, just like the sound card is prohibited by default. We don't need too many functions and port support. For example, some unnecessary and high-risk ports can be blocked. For some necessary and risky ports, such as ports 3389 and 80, we can set them as non-special secret ports by modifying the registry, so that the security hidden dangers of server ports no longer exist.
