System webpage is not open, troubleshooting steps

One, the problem of network setup
 
This causes more than the need to manually specify IP, gateway, DNS server networking, and use proxy server to surf the Internet. Double-check your computer's network settings.
 
Second, the problem of DNS server
 
When IE is unable to browse the Web page, you can first try to access the IP address, if you can access, then it should be the problem of DNS, the problem may be caused by DNS to get DNS error or DNS server itself problems, At this point you can specify the DNS service manually (the address can be the DNS server address provided by your local ISP, or you can use the DNS server address elsewhere.) ) in the properties of the network, (Control Panel-Network and Dial-up Connections-local connections-right-click Properties-TCP/IP Protocol-Properties-use the following DNS server address). Different ISPs have different DNS addresses. Sometimes it is a router or network card problem, unable to connect with the ISP's DNS service, in this case, you can shut down the router for a while to open, or reset the router.
 
Another possibility is that there is a problem with the local DNS cache. In order to improve the speed of website access, the system will automatically save the website that has been visited and obtain the IP address into the local DNS cache, once again access to the site, it is no longer through the DNS server and directly from the local DNS cache to remove the site's IP address for access. Therefore, if there is a problem with the local DNS cache, it can cause the Web site to become inaccessible. You can perform ipconfig/flushdns in run to rebuild the local DNS cache.
 
Third, the problem of IE browser itself
 
When the IE browser itself fails, it will naturally affect the browsing, or IE is corrupted by malicious modification will also cause the Web page cannot be browsed. At this point you can try to use "Huangshan IE repair expert" to repair (recommended to Safe Mode repair), or re-ie (such as the re-installation of IE encountered the problem can not be re-installed, refer to: With a resolution can not reinstall IE)
 
Iv. Problems with network firewalls
 
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, etc., you can try to check the policy, reduce the firewall security level or directly shut down the test is back to normal.
 
V. Network protocol and NIC driver issues
 
IE cannot be browsed, it is possible that the network protocol (especially TCP/IP protocol) or NIC driver damage caused, you can try to re-NIC driver and network protocol.
 
Vi. issues with the Hosts file
 
The Hosts file is modified, it also causes the browsing is not normal, 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, can be repaired by using the SFC command, the WIN98 system can execute SFC in "Run", then perform the scan; win2000/xp/2003 executes SFC in "Run" Scannow try to fix it.
 
When only IE cannot browse the Web page, and QQ can be on, it is often due to winsock.dll, Wsock32.dll or Wsock.vxd (VxD only exist under the Win9x system) files such as corruption or loss caused, Winsock is composed of tcp/ IP protocol is an important part of the general need to reload the TCP/IP protocol. However, XP begins to integrate the TCP/IP protocol, so it cannot be reinstalled as simple as 98, and you can use the Netsh command to reset the TCP/IP protocol back to the state it was in when the operating system was first installed. Here's how:
 
Click "Start Run", enter "CMD" command in the Run dialog box, pop up the command Prompt window, then enter "netsh int ip reset c:\resetlog.txt" command to return, where "Resetlog.txt" The file is the log file used to record the result of the command execution, which must be specified, and the full path to the log file specified here is "C:\resetlog.txt". The result of executing this command is the same as the effect of removing and reinstalling the TCP/IP protocol.
 
Tip: The netsh command is a command-line-based scripting tool that you can use to configure and monitor Windows systems, and it also provides an interactive network shell interface, using the format of the Netsh command in the Help file (enter "netsh/?" in the prompt window). Can).
 
The second solution is to repair the above file, Win9x use SFC to extract the above files, win2000/xp/2003 use the Sfc/scannow command to repair the file, when the Sfc/scannow cannot be repaired, You can try the online release of the repair tool specifically for this issue winsockfix, can be searched online download.
 
Eight, real-time monitoring of anti-virus software problems
 
This is not often seen, but sometimes it really is related to real-time monitoring, because now antivirus software real-time monitoring has added to the content of the Web monitoring. To cite an example: KV2005 will be on the individual machine will cause IE can not browse the Web page (many friends have encountered), its specific performance is as long as the web monitoring, a power on the internet about 20 minutes later, IE will not be able to browse the Web, at this time if the KV2005 web monitoring off, everything back to normal , the KV2005 can not be solved after completely reloading. Although not installed KV2005 each machine will appear this problem, after all, the system of each machine is different, the installation of the program is not the same. But if IE cannot browse the webpage, also should pay attention to check the anti-virus software.
 
Ix. Problems of application Management Services
 
Appear only on QQ can not open the situation, restart after the good. However, even if the restart, open 7 to 8 pages and can not open the page, only on QQ. Sometimes telecom will often let you disable application Management service, you can solve. The specific reason is unclear.
 
Ten, the infection caused by the virus
 
This is often the case when opening ie, in the left-hand box of the IE interface, prompted: Opening the Web page, but long time not responding. In the task Manager to see the process, (into the method, put the mouse on the taskbar, right-Task Manager-process) to see how the CPU occupancy rate, if it is 100%, can be sure, is infected with the virus, then you want to run other programs simply suffer. This is to find out which process is greedily consuming CPU resources. After finding, it is best to record the name, and then click End, if not end, you want to boot into safe mode to delete the east, but also to enter the registration table, (method: Start-run, input regedit) in the Registry dialog box, click Edit-Find, enter the program name, found, click the right mouse button delete, Then a few more searches, often can be completely removed clean.
 
There are a lot of viruses, antivirus software is powerless when the only way is to manually delete.
 
Xi. Unable to open level two link
 
There is also a phenomenon need to pay special attention: is to open the homepage of the site, but can not open two-level links, if so, the method is to re-register the following DLL file:
 
In the start-run input:
 
regsvr32 Shdocvw.dll
 
regsvr32 Shell32.dll (Note this command, do not lose first)
 
regsvr32 Oleaut32.dll
 
regsvr32 Actxprxy.dll
 
regsvr32 Mshtml.dll
 
regsvr32 Urlmon.dll
 
regsvr32 Msjava.dll
 
regsvr32 Browseui.dll
 
Note: Press ENTER for each entry. The second command can not lose, after losing these commands to restart Windows, if found invalid, and then re-enter again, this time enter the second command.
