Common causes and solutions for Internet browsing failures of IE

Common causes and solutions for Internet browsing failures of IE
　　
I. Network Settings
　　
This is because you need to manually specify the IP address, gateway, and DNS server connection mode, and use the proxy server to access the Internet. Carefully check the computer's network settings.

Sometimes the proxy server is set incorrectly, which may cause the webpage to fail to be opened. You can view and modify the proxy server settings in the connection settings under Internet Options in IE.
　　
Ii. DNS server problems
　　
When ie cannot browse the Web page, try the IP address first. If yes, it should be a DNS problem, the DNS problem may be caused by an error in obtaining the DNS when the network is connected or a problem with the DNS server itself. In this case, you can manually specify the DNS Service (the address can be the DNS server address provided by your local ISP, you can also use the DNS server address in other places .) In the network properties, (Control Panel-network and dial-up connections-local connection-right-click Properties-TCP/IP protocol-properties-use the following DNS server address ). Different ISPs have different DNS addresses. Sometimes it is a problem with the vro or Nic and cannot be connected to the DNS Service of the ISP. In this case, you can turn the vro off for a while or reset the vro.
　　
Another possibility is that the local DNS cache is faulty. To speed up Website access, the system automatically saves a website that has been accessed and obtained an IP address to the local DNS Cache. Once the website is accessed again, then, the IP address of the website is not directly retrieved from the local DNS Cache through the DNS server for access. Therefore, if a problem occurs in the local DNS cache, the website cannot be accessed. You can execute ipconfig/flushdns in "run" to recreate the local DNS cache.

Domain name resolution errors are also one of the common causes of failure to open a webpage. When a computer performs domain name resolution, it first needs to access the hosts file of the Local Machine. Usually some viruses will modify this file to shield some websites, especially anti-virus websites. The hosts file is in the "C:/Windows/system32/Drivers/etc" directory by default. You can use "Notepad" to open it. Generally, the content below "127.0.01 localhost" can be deleted.

If there is no problem with hosts, it may be due to DNS settings. Generally, you can set it to automatically retrieve DNS for ADSL or dial-up Internet access.
　　
Iii. Problems with IE browser
　　
When the IE Browser fails, browsing is naturally affected, or the IE is maliciously modified or damaged, leading to the inability to browse the Web page. At this time, you can try to fix it with Kingsoft Security Assistant.
　　
Iv. Network Firewall Problems
　　
If the network firewall is improperly set, for example, the security level is too high, ie is accidentally put into the blocked access list, or the firewall policy is incorrect, you can try to check the policy, reduce the firewall security level, or directly turn it off and try to restore the normal state.
　　
V. network protocol and NIC Driver Problems
　　
IE cannot be browsed. It may be caused by network protocol (especially TCP/IP Protocol) or network card driver damage. You can try to re-drive the network card and network protocol.
　　
Vi. Hosts file Problems
　　
The modification of the hosts file also causes abnormal browsing. The solution is to clear the content in the hosts file.
　　
VII. System File Problems
　　
When the system files related to IE are replaced or damaged, the normal use of IE will be affected. You can use the SFC command to fix this problem. The Win98 system can execute SFC in "running, then run the scan. For Win2000/XP/2003, run SFC/scannow in "run" to try to fix the problem.
　　
When only ie cannot browse the Web page while QQ can access it, it is often caused by Winsock. DLL, wsock32.dll, or wsock. vxD (VxD only exists in the Win9x system) and other files are damaged or lost. Winsock is an important part of the TCP/IP protocol. Generally, the TCP/IP protocol must be reinstalled. However, XP began to integrate the TCP/IP protocol, so it cannot be simply uninstalled and reinstalled like 98. You can use the netsh command to reset the TCP/IP protocol, restore it to the status when the operating system is installed for the first time. The procedure is as follows:
　　
Click "start running", enter the "cmd" command in the "run" dialog box, and enter "netsh int IP reset resetlog.txt" or "netsh int IP reset C: the/resetlog.txt file is used to record command execution results. This parameter must be specified. The complete path of the specified log file is "C: resetlog.txt ". The result of executing this command is the same as deleting and re-installing the TCP/IP protocol.

The reset parameter may be replaced with reset all in 2000, that is, "netsh int IP reset all C:/resetlog.txt ".

　
Tip: The netsh command is a command line-based scripting tool. You can use this command to configure and monitor Windows systems. In addition, it provides an interactive network shell program interface, for the format of the netsh command, see the Help File (enter "netsh /?" ).
　　
The second solution is to fix the above files. Win9x uses SFC to re-extract the above files. Win2000/XP/2003 uses the SFC/scannow command to fix the files. When SFC/scannow cannot be used to fix the files, you can try winsockfix, a special fixing tool released on the Internet.
　　
VIII. applicationmanagement service problems
　　
When the web page cannot be opened only on QQ, You can restart it. However, even if it is restarted, after opening 7 to 8 web pages, you can only go to QQ. Sometimes China Telecom often allows you to disable the applicationmanagement service. The specific cause is unknown.
　　
9. Virus Infection
　　
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.
　　
10. Another phenomenon also needs to be paid special attention: the homepage of the website can be opened, but the second-level link cannot be opened. If so, the solution is to re-register the following DLL file:
　　
Enter:
　　
Regsvr32shdocvw. dll
　　
Regsvr32shell32. dll (note that you do not need to enter this command First)
　　
Regsvr32oleaut32. dll
　　
Regsvr32actxprxy. dll
　　
Regsvr32mshtml. dll
　　
Regsvr32urlmon. dll
　　
Regsvr32msjava. dll
　　
Regsvr32browseui. 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.

11. ie damaged

If you can use QQ to access the Internet, you can use other browsers such as Firefox and opera to open the web page. If you only have IE to browse, most of them are damaged. You need to reinstall IE.

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.

For 98 or 2 k systems, if the IE version is 5.0, we recommend that you upgrade it to 6.0.

If 6.0 has been installed on the 98 system, 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, expand hkey_local_machinesoftwaremicrosoftactive setupinstalled COMPONENTS {89820200-ecbd-11cf-8b85-00aa005b4383}, and change the isinstalled DWORD value to 0;

2. Open the Windows XP installation disc and enter "rundll32.exe setupapi" and "installhinfsection defaultinstall 132% WINDIR % infie. inf" at the startup and runtime"

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

12. System Winsock communication component faults

About 80% of web pages cannot be opened on QQ are damaged by the Winsock component. There are several causes of component damage: virus causes, incomplete anti-virus software virus sequelae, Pirated Windows XP, operating system patch installation faults, and abnormal system restoration.
For Windows/XP, click the Start menu, select Run, enter SFC/scannow, and click OK;
For Windows 98/Me, enter "SFC ". The system automatically checks the replaced system components and restores them. You need to insert the installation disc of the system.

You can also try a free repair software named "Winsock fix ". You only need to run the software and follow the prompts to perform operations step by step. Generally, the failure to open the webpage due to damage to the Winsock component can be solved.
