Win7 pops up "Cannot find server or DNS error" prompt what to do?

Xiaobian recently used the Win7 system, several times to open the web page pops up "can not find the server or DNS error" window, but other software such as QQ can be used normally. How to solve this?

The method is as follows:

(1) Use nslookup to determine whether it is a DNS resolution fault: (This step is to confirm whether it is caused by a DNS error)

To be 100% judged whether the DNS resolution failure is solved by the system's own NSLOOKUP.

Step 1: Enter "Start-> Run-> Enter CMD" and press Enter to enter command line mode.

Step 2: Enter the nslookup command and press Enter to enter the DNS resolution query interface.

Step 3: The command line window will display the DNS server address used by the current system, for example, 202.106.0.20.

Step 4: Next enter the domain name of the site you are unable to access. If you can't access it, DNS resolution should not work properly. We will receive a prompt message for DNS request timed out, timeout was 2 seconds. This shows that our computer does have a DNS resolution failure.

Tip: If the DNS resolution is normal, it will feedback back to the correct IP address.

(2) Check whether the DNS server works normally: (This step is to query your DNS, remember that the broadband should be connected)

At this time, we have to look at the DNS address used by our computer. How much is it, and query his running situation.

Step 1: Enter "Start-> Run-> Enter CMD" and press Enter to enter command line mode.

Step 2: Enter the ipconfig /all command to query the network parameters.

Step 3: In the ipconfig /all display information we can see a place that says "DNS server", this is our DNS server address. Step 4: If the internal network address of your company is displayed at the DNS server, then your company's DNS resolution is done to the internal DNS server. In this case, we need to check the DNS server in DNS. Perform nslookup operation on the server to see if it can be parsed normally. To solve the DNS service failure on the DNS server, the problem can generally be solved. Previous1234Next page Total 4 pages
