The Win7 system opens the web page and pops up "Cannot find server or DNS error".

Browsing the webpage makes us do things that we often do during the daily use of win7 system. Recently, some users have reported that they open under win7 system. When the webpage is popped up, it always pops up "cannot find the server or DNS error" window, which can not get online, but other software such as qq can be used normally. How to deal with this problem? Let me explain Win7 for everyone. Open the web page under the system to pop up “ can not find the server or DNS error & rdquo;

First, use nslookup to determine whether it is really a DNS resolution failure: (This step is to confirm whether it is caused by a DNS error), if you want to judge 100% of the DNS resolution failure, you need to pass the system's own NSLOOKUP To solve it.

1. Pass “Start->Run->Enter CMD" Enter and enter command line mode;

2. Enter nslookup command and press Enter to enter DNS resolution query. Interface;

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

4. Next, enter the domain name of the site that you cannot 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.

Second, query the DNS server work is normal: (This step is to query your DNS, remember to connect to the broadband), this time we have to look at the DNS address used by their computer, and query His operation.

1. Open under win7 system "Start->Run-> Enter CMD" Enter and enter command line mode;

2. Enter ipconfig /all command to query the network parameter.

3, in the ipconfig /all display information we can see a place to write "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.

The above is the detailed solution to open the web page under Win7 system "can not find the server or DNS error", users who encounter the above problems can refer to the above methods to try to solve it.
