WinXP system can be on qq but can't open the web page how to solve it?

Recently, users of WinXP system have reported that their computers can be QQ but they can't open the webpage. I don't know what caused it, and how to solve it. In fact, there will be such a situation, it is likely that the DNS server parsing error caused, of course, may be caused by other reasons. Below, let's take a look at the specific solution.

Method Steps

I. DNS Resolution Error

1. Click on the “Start” menu, click on “Control Panel” and double-click “Network Connection” ”.

2. Right-click & ldquo; Local Area Connection & rdquo; icon, the pop-up menu to select & ldquo; Properties & rdquo; command.

Second, set up a proxy server

1. some friends set up a proxy server resulting in open Web pages, and QQ using a 4000 port, access to the Internet using a 80 or 8080 port, so this is why it can be used on qq but can't open the webpage.

2. Right-click on the Internet Explorer icon on the desktop and open the menu and click on the "Properties" command.

3. Open the & ldquo; Internet Properties & rdquo; window, switch to the & ldquo; connection & rdquo; tab, click & ldquo; LAN Settings & rdquo; button.

Third, for other reasons

1. viral infection

Many viruses can cause not hit the pages of phenomena, such as infection associated with IE components, disguised as IE plugin, etc., open the task manager to view the IE process, you will find that the CPU usage has risen sharply, even reaching 100%. This situation is definitely a virus Trojan, please upgrade the antivirus software to the latest version, and then check the whole process. kill.

2. Problems with the IE browser itself

IE kernel damage or related component damage will naturally lead to problems browsing the web, then the best way is to search the online repair IE tool or Reinstall IE directly.

3. Network firewall problems

If the security level of the network firewall is set too high or IE's security policy is set, blocking the operation of IE will also cause the web page to be opened.

4. Network protocol and network card driver problems

IE can not open the web page may be caused by network protocol (especially TCP /IP protocol) or network card driver damage, then you can reinstall Network protocol or network card driver to restore it to the default configuration.

5. System file problems

If the system file associated with IE browser is damaged or lost, it can cause qq but can't open the webpage. At this time, we can use “ sfc /scannow & rdquo; command to repair the system files

These are under WinXP system but can not open the qq solutions page, after the above steps, I believe we can solve the problem, need to pay attention Adding code that blocks access to a website in a HOSTS file can also cause a web page to be opened, but this is limited to a web page.
