The first time you contact the computer should be to check some information online. The first software you contact should be IE browser. You also know that the Internet option in IE browser is very important. It sets many important properties. The following is some relevant information about the Internet option of IE browser that I sorted out. I hope it will be helpful to you!
1. Under win7 system, use Win + R key to call up the operation dialog box, and then enter gpedit in the operation window MSc command, open the local group policy editor;
2. In the local group policy editor, expand "user configuration" - "management template" - "Internet Explorer" - "browser menu" successively;
3. Then find "Tools menu: disable Internet option" in the right pane, double-click to open it and set it to "disabled", then save and exit the local group policy editor.
I. the problem of network setting. This reason mostly occurs when you need to manually specify the networking mode of IP, gateway and DNS server, and use proxy server to surf the Internet. Check your computer's network settings carefully.
Second, the problem of DNS server. When ie cannot browse the web page, you can try to access it with IP address first. If you can access it, it should be the problem of DNS. The problem of DNS may be the error of obtaining DNS during networking or the problem of DNS server itself, At this time, you can manually specify the DNS service (the address can be the DNS server address provided by your local ISP, or the DNS server address that can be used normally in other places. Do it in the network properties (control panel - network and dial-up connection - local connection - right click Properties - TCP / IP protocol - properties - use the following DNS server address). Different ISPs have different DNS addresses. Sometimes it's the problem of the router or network card, which can't connect with the DNS service of the ISP. In this case, turn off the router for a while, or reset the router. Another possibility is that there is a problem with the local DNS cache. In order to improve the access speed of the website, the system will automatically store the website that has been visited and obtained the IP address into the local DNS cache. Once the website is accessed again, the IP address of the website will be directly extracted from the local DNS cache instead of through the DNS server. Therefore, if there is a problem with the local DNS cache, the website will be inaccessible. You can rebuild the local DNS cache by executing ipconfig / flushdns in run.
III. problems of IE browser itself. When the IE browser itself fails, it will naturally affect browsing; Or ie is maliciously modified and damaged, which will also lead to inability to browse the web page. At this time, you can try to use the "Internet assistant ie repair expert" to repair, or re ie (see the IE reinstallation skills of this site)
IV. problems of network firewall if the network firewall is not set properly, such as the security level is too high, ie is accidentally put into the blocked access list, wrong firewall policies, etc., you can try to check the policies, reduce the security level of the firewall or turn it off directly to try to restore normal.
V. problems with network protocol and network card driver ie can't browse, which may be caused by the damage of network protocol (especially TCP / IP Protocol) or network card driver. You can try to restart the network card driver and network protocol.
Vi. the problem of the hosts file. If the hosts file is modified, it will also lead to abnormal browsing. Of course, the solution is to empty the contents of the hosts file.
VII. Problems with system files. When the system files related to IE are replaced or damaged, it will affect the normal use of ie. at this time, SFC command can be used to repair it. Win98 system can execute SFC in "operation" and then scan; Win2000 / XP / 2003 performs SFC / scannow attempt repair in "operation" (you can query WinXP repair skills of this site). Among them, when only ie can't browse the web and QQ can go on, it is often due to Winsock dll、wsock32. DLL or wsock VxD (VxD only exists in Win9x system) and other files are damaged or lost. Winsock is an important part of TCP / IP protocol. Generally, TCP / IP protocol should be reinstalled. However, XP starts 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 to restore it to the state when the operating system was first installed. The specific operations are as follows: click "start running", enter the "CMD" command in the running dialog box, pop up the command prompt window, and then enter the "Netsh int IP reset C: \ resetlog. TXT" command. The "resetlog. TXT" file is the log file used to record the execution results of the command. This parameter option must be specified. The full path of the log file specified here is "C: \ resetlog. TXT". The result of executing this command is the same as that of deleting and reinstalling TCP / IP protocol. Tip: Netsh command is a scripting tool based on the command line. You can use this command to configure and monitor the windows system. In addition, it also provides an interactive network shell program interface. For the use format of Netsh command, please refer to the help file (enter "Netsh /?" in the command prompt window) OK). The second solution is to repair the above files. Win9x uses SFC to re extract the above files. WIN2000 / XP / 2003 uses CMD / C SFC / scannow command to repair the files. When CMD / C SFC / scannow cannot be used to repair, you can try winsockfix, a repair tool specially released on the Internet for this problem, which can be searched and downloaded on the Internet.
VIII. The problem of real-time monitoring of anti-virus software is not common, but sometimes it is related to real-time monitoring, because now the real-time monitoring of anti-virus software adds the monitoring of web content. But if ie can't browse the web, you should also check the anti-virus software.
IX. there is a problem with the application management service. You can only go to QQ and can't open the web page. Just restart it. But even if you restart, you can't open a web page after opening 7 to 8 web pages. You can only go to QQ. Sometimes Telecom often makes you disable the application management service, which can be solved.
X. This situation is often caused by virus infection. When you open IE, you will be prompted in the lower left box of the IE interface: you are opening a web page, but you haven't responded for a long time. Check the process in the task manager (enter the method, put the mouse on the taskbar, and press the right button - Task Manager - process) to see how the CPU utilization rate is. If it is 100%, it is certain that it is infected with a virus. At this time, you want to run other programs, which is just suffering. This is to find out which process greedily occupies CPU resources After finding it, you'd better record the name, and then click finish. If you can't finish it, you should start to delete it in safe mode and enter the registry. (method: start - run, enter regedit) in the registry dialog box, click Edit - search, enter the program name, find it, click the right mouse button to delete it, and then search several times, which can often be completely deleted. Many viruses, when the anti-virus software is powerless, the only way is to delete them manually.
