What can I do if I cannot open IE?

Why cannot I open IE?

Cause 1: The browser cannot open the webpage due to incorrect iesettings. For example, if you use the IE proxy, choose Tools> internet> connection, check whether connections or proxies that cannot be used are loaded by default.

 
Cause 2: System files infected with Trojans are cleared by anti-virus software as Trojans, which may cause problems such as failure of ie browser and failure of ie.
 
Cause 3: the DNS server of the local carrier may be adjusted. This type of problem usually occurs when the IP address is allocated statically. The IP address configuration in the "DNS" setting of the local connection has expired, how to troubleshoot this problem: ping 8.8.8.8.8 (this address is a public DNS address provided by Google). If it is accessible, it indicates that it is a DNS setting problem; the link may be faulty.

 
Cause 4: The Web page cannot be opened by the IE kernel browser due to incorrect operation of the IE component.

Cause 5: 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. In this case, you can try to use "iefix" (It is recommended to fix it in security mode), or re-run IE (for example, if you encounter a problem that cannot be re-installed when re-installing IE, refer to: Appendix 1 to solve the problem that cannot be re-installed)

Cause 6: 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.

Cause 7: 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.

Cause 8: HOSTS File problems

The modification of the HOSTS file also causes abnormal browsing. The solution is to clear the content in the HOSTS file.

Solution to IE browser failure

1. The IE browser component cannot open the webpage due to virus modification, making the local machine unable to access some specified websites. Download kingsoft guard, which includes the browser repair function. After installation, click "scan Trojan" to use the quick scan function.

 
2. Internet Explorer cannot open the webpage due to a DNS error. This is usually due to a DNS server issue or a dns server address set by the user is incorrect. For users who use broadband Internet access, dns is automatically obtained. If such users cannot open webpages through qq, you can use ipconfig/flushdns to obtain them again; or set the dns server address to 8.8.8.8 (this is the free domain name resolution server address provided by Google ). If a user in the Lan cannot open the webpage and is notified of a DNS error, most of the messages are due to gateway configuration problems and need to be resolved by the network administrator.

 
3. You can open the home page, but you cannot click the secondary link. Most of these problems are caused by the lack of IE components. The solutions include:

 
A. Register the IE component again. Open the "Start" menu -- run -- enter regsvr32 jscript. dll and press Enter. If a success prompt is displayed, enter regsvr32 vbscript. dll and press enter.

 
B. Install a third-party non-IE core browser or upgrade IE to the latest version.

If the above method cannot be solved, we can try the following methods first.

1. First, check whether the problem can be solved: open the browser and click "tools" & rarr; INTERNET Options & rarr; regular page & rarr; delete cookies & rarr; delete files & rarr; select and delete all offline content & rarr; OK & rarr; Clear History & rarr; OK. Tool & rarr; INTERNET Options & rarr; content & rarr; clear SSL & rarr; clear password & rarr; OK & rarr; automatically complete & rarr; clear form & rarr; clear password & rarr; OK & rarr; close all open browser windows & rarr; restart the browser.

2. Do the following to solve the problem: open the browser, click "tools" & rarr; "Manage Add-on" to disable all suspicious plug-ins, or you can know exactly what to keep. Then & rarr; Tool & rarr; INTERNET Options & rarr; general page & rarr; delete cookies & rarr; delete files & rarr; select and delete all offline content & rarr; confirm & rarr; set the disk space to 8 MB or less (I use 1 MB for IE6) & rarr; OK & rarr; clear historical records & rarr; the number of days when the web page is stored in the history record: 3 or less & rarr; the application is OK (I set it to 0 days ).

3. Check whether your browser has been maliciously attached with a plug-in & rarr; uninstall and clear it.

4. (this entry is for IE6) run & rarr; regedit & rarr; to enter the registry, go to & rarr;
Hkey_local_machinesoftwaremicrosoftwindowscurrentversionpolicershellexecutehooks
This location has a normal key value {AEB6717E-7E19-11d0-97EE-00C04FD91972}, and there is a "default" retained; delete others. (Of course, there is also a simple and effective method here, that is, to download 360 security guard, you can directly use 360 -- advanced -- repair IE and click repair. The above step can also use 360 of malicious plug-ins to help you identify a malicious plug-in. Currently, the Internet Explorer cannot be opened, which is often caused by the installation of malicious plug-ins)

5. Register the ie dll and run the following command: open "run" and enter & rarr; cmd & rarr; press Enter.

For % I in (% windir % system32 *. dll) do regsvr32.exe/s % I press enter
For % I in (% windir % system32 *. ocx) do regsvr32.exe/s % I press enter
Restart the machine after the two operations are completed. If the IE browser cannot be opened, execute the following method.

6. Completely re-register the DLL, open "run" input & rarr; cmd & rarr; press enter

Then copy the following line of characters to the black cmd box and press enter to wait for the dll file to be fully registered. To prevent input errors, copy this command, right-click the command prompt and choose & rarr; paste & rarr; press Enter. Wait until the screen stops rolling.
For % 1 in (% windir % system32 *. dll) do regsvr32.exe/s % 1
Then restart the machine.

7. Reinstall IE

Reinstall the self-contained IE6.0 browser on Windows XP
Windows has many IE browser vulnerabilities, which are the most prone to problems. Sometimes it cannot be solved, so you can only reinstall it. There are two methods to reinstall IE 6.0:
Method 1: Open registry editor and find [HKEY_LOCAL _ MACHINE \ SOFTWARE \ Microsoft \ Active Setup \ Installed Components \ {89820200-ECBD-11cf-8B85-00AA005B4383}], change the DWORD value of IsInstalled to 0.
Method 2: Use the Rundll32 command to easily reinstall the instance. We will reinstall IE6.0 in Windows XP as an example:
First, insert the Windows xp cd into the optical drive, and then click the "start & rarr; run" command. In the "run" dialog box, enter "Rundll32 setupapi, InstallHinfSection DefaultInstall 132 C: windowsinfie. inf "command. After you press enter, the system will open the installation process dialog box and start to reinstall IE6.0.
Tip: If your Windows XP system is not installed on drive C, change "CWindowsInfIe. inf" to "% systemroot % infie. inf ".
If a later version of Internet Explorer such as Internet Explorer 8 is installed in Windows XP, find Internet Explorer 8 in the add or uninstall programs and download Internet Explorer 8 from the web browser.
For VISTA and Windows 7 systems, you only need to download IE8 again. Of course, the reason why ie cannot be opened is also many reasons. These methods can effectively solve the common symptoms of browsers cannot be opened.
