Why Internet Explorer is not on internet

First, the network setup problem

This reason is more than the need to manually specify the IP, gateway, DNS server networking mode, and using a proxy server to access the Internet. Carefully check your computer's network settings.

　　Second, network protocol and the problem of NIC driver

IE can not browse, there may be network protocol (especially TCP/IP protocol) or network card driver damage caused, can try to reconnect the network card driver and network protocol.

　　Third, DNS server issues

When IE can not browse the Web page, you can try to access the IP address, if you have access, then it should be a DNS problem, causing DNS problems may be connected to the network when the DNS error or the DNS server itself problem, then 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 can be used elsewhere. In the properties of the Network (Control Panel-Network and dialing connections-Local Area Connection-right key property-TCP/IP protocol-Properties-use the following DNS server address). Different ISPs have different DNS addresses. Sometimes it is a problem with a router or network card that is unable to connect to the ISP's DNS service, which allows the router to be shut down for a while, or to reset the router.

Another possibility is that there is a problem with the local DNS cache. In order to improve the speed of Web site access, the system will automatically have visited and obtain the IP address of the site into the local DNS cache, once the site is accessed, it is no longer through the DNS server and directly from the local DNS cache to remove the IP address of the site to access. Therefore, if there is a problem with the local DNS cache, it can cause the Web site to be inaccessible. You can perform ipconfig/flushdns in run to rebuild the local DNS cache.

　　Four, the network firewall problem

If the network firewall is not set up properly, such as high security level, accidentally put IE into the block access list, the wrong firewall policy, and so on, you can try to check the policy, reduce the firewall security level or directly turn off the test is back to normal.

　　V. Issues of the Hosts document

The Hosts file is modified, will also cause the browsing is not normal, the solution is of course, the contents of the Hosts file empty.

　　VI. Issues of System documentation

When the system files related to IE are replaced or damaged, it will affect the normal use of IE, you can use the SFC command to repair, WIN98 system in "Run" in SFC, and then perform a scan; Win2000/xp/2003 performs a sfc/scannow attempt to fix it in "run".

　　Seven, IE browser itself problem

When IE browser itself fails, it will naturally affect the browsing, or IE can be malicious modification of the damage will also cause the Web page can not be browsed. At this point you can try to use the "IE repair expert" to repair (recommended to repair in safe mode), or to reload ie.
