Solve the problem that the computer can access QQ but cannot open the webpage

Fault Cause

1. DNS server Setting errors, which are the most common errors.
2. TCP/IP protocol errors, which are also common.
3. Modem fault
4. Virus Infection
5. Related to proxy server settings
6. ie damaged

Solution

DNS server setting error
To troubleshoot the above 1st cases, you must first check whether the master DNS and secondary DNS in the dial-up network are incorrect, note that the "Dial-Up Network" DNS is checked instead of the "network" DNS in the "control panel". The following uses Windows98 as an example to describe other operating systems, it is nothing more than correcting the wrong DNS server address and reinstalling the TCP/IP protocol. The steps are as follows:

1. Double-click the "my computer" icon on the desktop to open a new window and double-click the "Dial-Up Network" icon in the window.

2. In the dial-up network window, find the icon you used to dial up the Internet, for example, "my connections". Right-click the icon ?, In the pop-up menu, click the left mouse button to select the bottom line "attribute ".

3. in the displayed window, click "server type". Note that in Windows98, the "Login network", "netbeui", and "IPX/SPX" options are selected by default, you need to remove these three options.

4. Click the "TCP/IP Settings" button in the lower right corner ?, In the displayed window, check whether there are black spots on the left side of "servers with allocated IP addresses" in the first line. If not, you must click with the mouse ?, In this window, there are two lines in Chinese: "servers with allocated name server address" and "server with specified name". In these two lines, the system must select one of them, if you select the line "specify the address of the name server", you need to pay special attention to see if the "Master DNS" and "secondary DNS" are set incorrectly, (The DNS for 163 of users in Guangzhou is: 202.96.128.68.) If an error is set here, you cannot browse the webpage, so you must change the error value. DNS refers to the domain name explanation server, and its function is to convert the English URL you enter in the browser into an IP address that can be recognized by the computer, you must ask your Internet Service Provider (if you are a 163 user, you can consult the local telecommunications department) about the address of their DNS server, enter the correct address here. If you cannot know what to fill in for "Master DNS" and "secondary DNS" at the moment, please select "servers with allocated name server addresses "?, Now, check whether the following two lines of Chinese "using IP header pointer compression" and "using the default gateway on the remote network" are checked? The two rows must be checked, and then click "OK" twice ".

Now, try to access the Internet through dialing and browse the webpage. Can you browse the webpage normally?

TCP/IP Protocol Error

Next, let's talk about the faults caused by problems with the TCP/IP protocol. If you check the above settings and find that the settings are correct, but you still cannot browse the Web page, then you need to check whether the "TCP/IP" protocol has an error. The method is as follows: double-click the "my computer" icon on the desktop ,? Double-click "Control Panel", find the "network" icon in the control panel, and double-click it? A new window will pop up, in the pop-up window, check whether the following network components have been installed x dial-up network adapter x TCP/IP. Pay special attention to the following two points: first, if the dial-up network adapter or TCP/IP is installed twice, the web page cannot be viewed? If you have already installed the dial-up network adapter, you will see a line that says "dial-up network adapter #2" or "TCP/IP-> dial-up network adapter #2 ", here there is an additional "#2", which means that you have installed it twice. If you find a line with "#2" like this, please delete this line.

Second, if the installation is not repeated, but the configuration in the dial-up network is correct, it is very likely that the TCP/IP protocol error will cause the browser to fail, the solution is to delete this protocol and re-install TCP/IP. (before this step, make sure that you have a Windows 9x installation disc, because the system needs to read data from this disc when you reinstall it ), you can click "dial-up network adapter" with the left mouse button. Note that there are three buttons in this window: "add", "delete", and "attribute ", click "delete". Then you will find that the "dial-up network adapter" has been deleted and check "TCP/IP". If you do not have other network adapters, after the dial-up network adapter is deleted, the TCP/IP will also be deleted. If you have installed other NICs, please left-click the line containing TCP/IP, delete them one by one. Click OK ". The system will ask you if you want to restart your computer and click "yes ". After restarting the computer, go to "Control Panel", double-click "network", return to the previous window, and click "add". A new window appears, in this window, select "adapter" and click "add". The last new window appears. The box on the left of this window is "vendor". Here, select "Microsoft", select "dial-up adapter" in the box on the right, and click OK, now you are back to the "Network Properties" window in the control panel, in addition, the "dial-up network adapter" and "TCP/IP" protocols have been added to "The following network components have been installed. Click "OK". The system may ask you to add the Windows 9x installation disc. After reading the data, you will be asked if you want to restart the computer. Click "yes" and restart the computer and then dial up the Internet, generally, faults that cannot browse the Web page will be ruled out.

Tip: Please note one of the above paragraphs that some of my friends have reported that after "TCP/IP" is reinstalled, they still cannot browse the Web page. We have tested and found that, the reason is that some friends immediately added "TCP/IP" in the window without restarting the computer after deleting "TCP/IP", and finally restarted the computer. This is futile. Remember to delete "TCP/IP", restart the computer, then add "TCP/IP", and then restart the computer again, in this way, the computer is restarted twice instead of once. Only in this way can the fault be solved.

Infected with viruses

This often occurs when you open ie. In the lower-left dialog box of the IE interface, the system prompts that the webpage is being opened, but the webpage does not respond for a long time. Check the process in the Task Manager (enter the method, place the mouse on the taskbar, right-click the Task Manager-process) to see how the CPU usage is. If it is 100%, you can be sure, if you want to run other programs, the virus is infected. Check which process occupies CPU resources greedily.

After finding it, you 'd better record the name and click "end". If it cannot be completed, you need to start to secure mode to delete the stuff and enter the Registry. (method: start-run, enter Regedit) in the Registry dialog box, click Edit-search, enter the program name, find it, right-click to delete it, And then perform several searches, it can often be completely deleted.

There are a lot of viruses. When anti-virus software is powerless, the only way is to manually delete them.

Related to setting proxy servers

In some cases, the proxy server (control panel -- Internet option-connection-LAN Settings-use proxy server for LAN) is set in the browser ), setting the proxy server does not affect QQ's network connection, because QQ uses port 4000 and port 80 or 8080 to access the Internet. This is why many people do not understand why QQ can be accessed, but web pages cannot be opened. The proxy server is generally not very stable, sometimes it can be accessed, sometimes it cannot. If so, cancel the proxy.

System File loss causes IE to fail to start properly

This phenomenon is quite common because

1. system instability is manifested in frequent crashes, frequent inexplicable restarts, and illegal shutdown, leading to loss of system files

2. Hardware and Software conflicts often occur when some programs are installed, causing NIC Driver conflicts or IE conflicts. Since Intel introduced hyper-threading CPU, a prominent problem is XP? IE6 in SP1 conflicts with hyper-threading;

3. system file damage or loss due to virus intrusion

In the first case, you can try to repair the system. In the 2 K or XP system, place the original installation disc (Note: The original installation disc must be used) and enter SFC in start-run? /Scanow. Press enter. 98 systems can also be checked using the SFC command.

In the second case, You Can unmount the recently installed hardware or program. 2 K or XP systems can press F8 after the machine is started to enter the Start Menu, select "Last correct configuration". If it is an XP system, you can also use the restoration function of the system to solve the problem quickly.

If the XP system is caused by hyper-threading CPU, you can disable hyper-threading In the BIOS or upgrade to SP2. (Of course, upgrading SP2 in XP involves a lot of knowledge and precautions, which will not be detailed here ). In this case, the ttbrowser that comes with QQ can be browsed normally. You can try it again.

In the third case, the system disk should be thoroughly scanned for viruses.

Another phenomenon also needs to be paid special attention: You can open the homepage of the website, but you cannot open the second-level link. If so, you can re-register the following DLL file:

Enter

Regsvr32? Shdocvw. dll

Regsvr32? Shell32.dll (note that you do not need to enter this command first.

Regsvr32? Oleaut32.dll

Regsvr32? Actxprxy. dll

Regsvr32? Mshtml. dll

Regsvr32? Urlmon. dll

Regsvr32? Msjava. dll

Regsvr32? Browseui. dll

Note: Press ENTER for each entry. The second command does not need to be input. After these commands are input, restart Windows. If it is invalid, enter the second command again. In addition, if it is a 98 system, it may be easier to download this file from the Microsoft website. The file is:

Http://download.microsoft.com/download/msn...us/mcrepair.exe?

IE damaged

If none of the above methods works, it may be that the kernel of IE is damaged. Although the system has been repaired and cannot be compensated, reinstalling IE is the best method.

If it is an XP system and the IE version is 6.0, we recommend that you upgrade it to 8.0.

If the XP system has been upgraded and installed with 8.0, click Add/delete programs in the control panel. A repair dialog box is displayed. Select the default repair and restart.

If it is a 2 K + ie6.0 or XP (the built-in IE is 6.0) system, re-ie is a little troublesome, there are two ways:

1. Open the registry and expand hkey_local_machinesoftwaremicrosoftactive? Setupinstalled? COMPONENTS {? 89820200-ECBD-11cf-8B85-00AA005B4383 ?}, Change the isinstalled DWORD value to 0;

2. Open the XP installation disc and enter “rundll32.exe at the start of the installation? Setupapi, installhinfsection? Defaultinstall? 132% WINDIR % infie. inf"

Note: reinstalling IE does not necessarily solve the problem. It is just a solution.
