One: the WinSock communication component of the system has failed. About 80% of the cases that QQ can't open the webpage are due to the destruction of Winsock components. Solution: If your operating system is Microsoft Windows 2000/XP, directly click the Start menu, select Run, and enter SFC/SANNOW for confirmation. Microsoft Windows 98/ME input "SFC" system will automatically check the replaced system components and repair them, during which users need to insert the operating system installation CD. Another method is to use repair software. The name is "Winsock Fix", just follow the prompts to operate correctly. \x0d\ 2: Domain name resolution error is also one of the common reasons why web pages cannot be opened. When a computer resolves a domain name, it must first access the computer's Hosts file, and then log in to DNS (Domain Name Resolution Server) for query. Therefore, it is necessary to check the local host file first. Usually some viruses will modify this file to block some websites. Hosts file is located in the user system directory, and the default address is: C: \ Windows \ System32 \ drivers \ etc "directory. (Assuming that the operating system is installed on the system drive C by default, I think you must install the system on the system drive C ~ ~ Hehe) Solution: We can open it with Notepad. In general, "anything below127.0.0.1localhost can be deleted". If there is nothing wrong with the host table, there may be something wrong with the DNS settings. Generally, you can set up ADSL or dial-up Internet to automatically obtain DNS. \x0d\ 3: IE browser is damaged. If QQ can surf the Internet, other browsers such as Firefox and Opera can also open web pages. Only IE can't browse, so the browser itself is mostly damaged. Solution: Reinstall IE browser \x0d\ 4: The proxy settings are incorrect. Sometimes the wrong proxy server may also cause the web page to fail to open. Solution: We can view and modify the settings of proxy server in the connection settings under Internet options of IE. Reason 5: Solve the virus cause: Upgrade the virus database of antivirus software, and then kill it. Summary: The above lists several reasons and solutions that may cause the computer to access QQ but not open the webpage, which can basically solve this problem. However, there may still be some other factors leading to this failure of the machine. At this time, users are advised not to format the computer casually. \x0d\ v. Problems with the network firewall \ x0d \ If the network firewall is set incorrectly, for example, the security level is too high, IE is accidentally put into the blocked access list, and the firewall policy is wrong, you can try to check the policy, lower the security level of the firewall or shut it down directly to see if it is back to normal. \x0d\ \x0d\ VI。 Network protocol and NIC driver problem \x0d\ IE can't browse, which may be caused by network protocol (especially TCP/IP protocol) or NIC driver damage. You can try resetting the network card driver and network protocol. \x0d\ \x0d\ VII。 There is something wrong with the HOSTS file \ x0d \ The modification of the hosts file will also lead to abnormal browsing. The solution, of course, is to empty the contents of the hosts file. \x0d\ x0d \ VIII。 System file problem \ x0d \ When the system files related to IE are replaced or damaged, it will affect the normal use of IE. At this point, you can use the SFC command to repair it. WIN98 system can execute SFC in "running" and then scan; WIN2000/XP/2003 tried to fix it by executing sfc /scannow in Run. \x0d\ Among them, when only IE can't browse the webpage, but QQ can, it is often caused by the damage or loss of files such as winsock.dll, wsock32.dll or wsock.vxd(VXD only exists under WIN9X system). Winsock is an important part of TCP/IP protocol, so it is generally necessary to reinstall TCP/IP protocol. However, xp began to integrate TCP/IP protocol, and it can't be simply uninstalled and reinstalled like 98. You can use the netsh command to reset the TCP/IP protocol and restore it to the state when you first installed the operating system. The specific operation is as follows: \x0d\ Click "Start Running", enter "CMD" command in the running dialog box to pop up the command prompt window, then enter "netsh int ip reset c:\resetlog.txt" command, and press enter, where "resetlog.txt" file is a log file to record the execution result of the command, and this parameter option must be specified. The daily record file specified here. The result of executing this command is the same as that of deleting and reinstalling the TCP/IP protocol. \x0d\ Tip: The netsh command is a scripting tool based on the command line. You can use this command to configure and monitor Windows systems. In addition, it provides an interactive network shell interface. For the format of netsh command, please refer to the help file (enter "netsh/?" In the prompt window. Just). \x0d\ The second solution is to repair the above files. WIN9X uses SFC to decompress the above files, and WIN2000/XP/2003 uses sfc /scannow to repair the files. When sfc /scannow can't fix them, you can try WinSockFix, a repair tool published on the internet specifically for this problem, which can be searched and downloaded online. \x0d\ x0d \ IX。 Real-time monitoring of antivirus software \ x0d \ This is not common, but sometimes it is related to real-time monitoring, because now the real-time monitoring of antivirus software increases the monitoring of web page content. For example: KV2005 will make IE unable to browse the web on personal computers (many friends have encountered it). Its specific performance is that IE can't browse the web page as long as it is turned on for about 20 minutes. At this time, if the web monitoring of KV2005 is turned off, everything will return to normal; KV2005 cannot be solved after complete reinstallation. Although not every machine with KV2005 installed will have this problem, after all, each machine has different systems and different installed programs. But if IE can't browse the web, you should also pay attention to checking antivirus software. \x0d\ \ x0d \ X. There is a problem with the application management service \ x0d \ You can only access QQ, but you cannot open the webpage. It will be fine after restarting. However, even if you restart, you can't open a webpage after opening 7 to 8 webpages, so you can only go to QQ. Sometimes telecommunications will let you disable the application management service, and it will be solved. The specific reason is unknown. \x0d\ \x0d\ XI。 Infected with virus \x0d\ This situation is often manifested in the lower left box of IE interface, which indicates that a webpage is being opened, but there is no response for a long time. View the process in Task Manager (input method, mouse on the taskbar, right click-Task Manager-Process) to see how CPU utilization is. If it is 100%, it can be determined that it is infected with a virus. At this time, if you want to run other programs, it is simply suffering. We need to find out which process greedily occupies CPU resources. When you find it, you'd better write down your name and click Finish. If you can't finish, you should start safe mode to delete this thing and enter the registry. (Method: Start-Run, enter regedit) In the registry dialog box, click Edit-Find, enter the program name, click the right mouse button to delete, and then conduct multiple searches. \x0d\ There are many viruses, and the only way is to delete them manually when antivirus software is powerless. \x0d\ \x0d\ XII。 Another phenomenon is that the secondary link cannot be opened: you can open the homepage of the website, but you can't open the secondary link. If this is the case, the solution is to re-register the following DLL file: enter: regsvr32 Shdocvw.dll regsvr32 shell32.dll (note this command, Regsvr32 Oleaut32.dll Regsvr32 Actxprxy.dll Regsvr32 Mshtml.dll regsvr32Urlmon.dll Regsvr32 Msjava.dll Regsvr32 Browseui.dll Note: For each entry, press Enter. You don't have to enter the second command first. After entering these commands, restart windows. If it is found to be invalid, enter it again, this time with a second command. \x0d\ XIII。 Clear the browser's historical data, and then check the network. This may be a network problem or your computer card.
