Unable to open webpage Processing

I. 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)

I often meet new friends there and hope you can join me.
Ii. DNS server problems
When ie cannot browse the Web page, try the IP address first. If yes, it should be a DNS problem, the DNS problem may be caused by an error in obtaining the DNS when the network is connected or a problem with the DNS server itself. In this case, you can manually specify the DNS Service (the address can be the DNS server address provided by your local ISP, you can also use the DNS server address in other places .) In the network properties, (Control Panel-network and dial-up connections-local connection-right-click Properties-TCP/IP protocol-properties-use the following DNS server address ). Different ISPs have different DNS addresses. Sometimes it is a problem with the vro or Nic and cannot be connected to the DNS Service of the ISP. In this case, you can turn the vro off for a while or reset the vro.

Another possibility is that the local DNS cache is faulty. To speed up Website access, the system automatically saves a website that has been accessed and obtained an IP address to the local DNS Cache. Once the website is accessed again, then, the IP address of the website is not directly retrieved from the local DNS Cache through the DNS server for access. Therefore, if a problem occurs in the local DNS cache, the website cannot be accessed. You can execute ipconfig/flushdns in "run" to recreate the local DNS cache.

Iii. Network Settings
This is because you need to manually specify the IP address, gateway, and DNS server connection mode, and use the proxy server to access the Internet. Carefully check the computer's network settings.

Iv. 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.
V. 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.
Vi. Hosts file Problems
The modification of the hosts file also causes abnormal browsing. The solution is to clear the content in the hosts file.
VII. System File Problems
When the system files related to IE are replaced or damaged, the normal use of IE will be affected. You can use the SFC command to fix this problem. The Win98 system can execute SFC in "running, then run the scan. For Win2000/XP/2003, run SFC/scannow in "run" to try to fix the problem.

When only ie cannot browse the Web page while QQ can access it, it is often caused by Winsock. DLL, wsock32.dll, or wsock. vxD (VxD only exists in the Win9x system) and other files are damaged or lost. Winsock is an important part of the TCP/IP protocol. Generally, the TCP/IP protocol must be reinstalled. However, XP began 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, restore it to the status when the operating system is installed for the first time. The procedure is as follows:

Click "start running", enter the "cmd" command in the running dialog box, and then enter "netsh int IP reset C: the resetlog.txt file is used to record the command execution result. This parameter must be specified. The complete path of the specified log file is "C: resetlog.txt. The result of executing this command is the same as deleting and re-installing the TCP/IP protocol.

Tip: The netsh command is a command line-based scripting tool. You can use this command to configure and monitor Windows systems. In addition, it provides an interactive network shell program interface, for the format of the netsh command, see the Help File (enter "netsh/" in the prompt window ).

The second solution is to fix the above files. Win9x uses SFC to re-extract the above files. Win2000/XP/2003 uses the SFC/scannow command to fix the files. When SFC/scannow cannot be used to fix the files, you can try winsockfix, a repair tool released on the Internet, to search and download it online.

VIII. Application Management Service Problems

When the web page cannot be opened only on QQ, You can restart it. However, even if it is restarted, after opening 7 to 8 web pages, you can only go to QQ. Sometimes, China Telecom often allows you to disable the application management service. The specific cause is unknown.

9. Virus Infection

This often occurs when you open ie. In the lower-left dialog box of the IE interface, the system prompts that the webpage is being opened, but the webpage does not respond for a long time. Check the process in the Task Manager (enter the method, place the mouse on the taskbar, right-click the Task Manager-process) to see how the CPU usage is. If it is 100%, you can be sure, if you want to run other programs, the virus is infected. Check which process occupies CPU resources greedily. after finding it, you 'd better record the name and click "end". If it cannot be completed, you need to start to secure mode to delete the stuff and enter the Registry. (method: start-run, enter Regedit) in the Registry dialog box, click Edit-search, enter the program name, find it, right-click to delete it, And then perform several searches, it can often be completely deleted.

There are a lot of viruses. When anti-virus software is powerless, the only way is to manually delete them.

10. Unable to open the second-level Link

Another phenomenon also needs to be paid special attention: You can open the homepage of the website, but you cannot open the second-level link. If so, you can re-register the following DLL file:

Enter:

Regsvr32 shdocvw. dll

Regsvr32 shell32.dll (note that you do not need to enter this command 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 does not need to be input. After these commands are input, restart Windows. If it is invalid, enter the second command again.

Can access QQ, but some web pages cannot be opened-the ultimate solution

1. The "connection" option of the browser is set incorrectly.

Solution: Set the Internet type correctly. If you use the proxy service to access the Internet, enter the IP address and port number of the proxy server correctly. If not, do not select "use proxy server.

2. DNS server setting error

Solution: If the ISP provider assigns you a fixed IP address, enter the IP address provided by the ISP and the DNS server address correctly. If the ISP provider assigns a dynamic IP address, therefore, you do not need to enter the DNS server address. Another possibility is that the DNS server of the ISP provider fails to correctly convert between domain names and IP addresses, in this case, you can enter the IP address of the website in the address bar of your browser to browse the webpage.

3. firewall setting error

Solution: If the firewall is improperly set, information exchange with the Internet may be blocked, resulting in failure to browse the Web page. You can modify the firewall settings. What, how to modify it? You can skip this. Well, let's talk about it. If you don't know anyone, simply select the default level and select "medium.

Case 2: solutions to faults in which ADSL can successfully log on but cannot browse the Web Page

First, we should check whether pingisp's DNS server address can be pinged. If pingisp can be pinged, most of them are software problems. If pingisp cannot be pinged, check the connection status of the hardware device/line and the Communication Protocol (TCP/IP)

If Ping is successful, you can see information similar to the following:

Command: Pinga. B .C. d

Replyfroma. B .C. D: bytes = 32 time = 14 msttl = 250

Replyfroma. B .C. D: bytes = 32 time = 27msttl = 250

Replyfroma. B .C. D: bytes = 32 time = 20 msttl = 250

Replyfroma. B .C. D: bytes = 32 time = 17msttl = 250

If Ping fails, the following information is displayed:

Pinginga. B. C. dwith32bytesofdata:

1. if you have multiple computers, you can replace them with other computers. Do not install any proxy server software or any firewall on the replaced computer, and install only one Nic to connect directly with adslmodem, install the ADSL dialing software correctly. Check whether browsing is normal. If yes, the fault is caused by the user's computer. If not, check whether the modem and line are normal.

2. if you have only one computer, you can stop running all proxy server software, such as Wingate, Sygate, and Windows Internet Connection Sharing (ICS). Log On directly to see if the fault can be rectified, if you stop running the agent server software and then troubleshoot it, it must be a problem with the agent service software.

3. Check the browser settings, especially the IE settings. For example, the most common failure that causes the browser to fail to browse the Web page is to select "Automatic Detection Settings" in IE. Remember not to select this option. For ie5x, Click Tools-> intrenet options-> connection-> LAN Settings. You can see this option. If this option is checked, you must cancel it. After cancellation, the fault can be solved.

4. check whether the TCP/IP protocol attribute settings, especially the DNS server settings are correct. Note that the DNS settings vary depending on the dialing software, some (set in the connection icon attribute of the dial-up network, some in the control panel network, and some in the connection profile attribute of the dial-up software (such as enternet300. Make sure that the settings are correct.

5. if you have confirmed the correctness of the above checks, you can prepare the ADSL dial-up software and Windows System CD, and then delete the dial-up software first, delete all TCP/IP protocols in the control panel/network, restart the computer, re-Add the TCP/IP protocol, turn on the modem power, and re-install the dialing software. After testing, if the settings are correct, after the dialing software and TCP/IP are reinstalled, most of them can solve the problem of dialing but not browsing the Web page.

6. Change a browser software, such as Netscape Browser browser test of Netscape.

7. If the computer on which you directly connect to adslmodem to access the Internet is equipped with two NICs, try to pick up the NIC connected to the local network first and leave only the NIC connected to adslmodem. Check whether the fault is rectified. If the fault is rectified, check the network and system resource configuration. In particular, check whether the NIC conflicts with other devices (for Windows users, you can check whether the device is normal on the control panel, system, or device management)

8. Your Nic enables the boot function of the bootrom chip, and this is caused by the NIC with the PXE boot chip. It can be solved as follows:

① If the NIC is integrated on the motherboard or the boot program on the internet is written into the bios, you can modify the boot sequence of the system from the BIOS settings, such as setting the hard disk to boot first, or, disable the NIC from starting the system from the BIOS.

② If the NIC is not integrated, You can unplug the boot chip on the NIC or use the NIC setup program to disable the bootrom boot function of the NIC. After the NIC is started, when "PressShift-F10Configure... appears ...... ", immediately press the" Shift + F10 "key combination, enter the menu, set bootorderrom to disable from row 4th, and then press F4.

Case 3: shared Internet access cannot browse webpages

After using a host in Windows XP as a proxy server, other computers in the LAN cannot browse the Web page. However, if data streams exist, QQ and other software can be used, and machines in the network can also access each other. The proxy server is a dual nic. in the Network Configuration Wizard, it is set to "other computers in the network access the Internet through the Local Computer" (connect to the LAN through a NIC ), in the shared property, set it to "B connections shared to the network" (that is, 2nd, B Nic ). The client is set to "access the Internet through other computers in the network". The operating system has Windows 98/2000/XP and is connected through a switch. The indicator lights on the proxy server are working properly (A, B, and broadband modem connections), but the indicator lights on the client occasionally. When you open a webpage, You can see "opening..." in the status bar.
* ***** The webpage is invisible for a long time, and the prompt "the webpage cannot be displayed" is displayed.

Solution: Your network connection and DNS settings may have problems:

① Establish a cascade line and connect network card a directly to the broadband ADSL.

② Set the IP addresses of other clients to 192.168.0.2, 192.168.0.3, 192.168.0.4 ......, set the subnet mask to 255.255.255.0, set the gateway address of each client to 192.168.0.1, and set DNS to your ISP's DNS address.

At the same time, you can also consider whether there is a conflict between the proxy server and the network card, change the PCI slot, remove unnecessary peripherals, and so on, it is also helpful to solve the problem.

Common ADSL disconnection

Web pages cannot be opened, downloads are interrupted, or online video and audio streams are interrupted. These problems may cause many users to access the Internet through ADSL. However, when you carefully check the adslmodem status, you will find that the dial-up logon is successful. So what exactly is the problem?

1. Line instability
If the domicile is too far away from the Telecommunications Bureau (more than 5 kilometers), you can report to the telecommunications department. Ensure that the line connection is correct (the connection methods for different voice splitters are different. Please follow the instructions to connect correctly ). At the same time, ensure that the communication quality of the line is good and there is no interference with other devices that may cause line interference, such as telephone extensions and fax machines. Check whether there is poor contact between the junction box and the crystal head, and whether there is any link with other wires. It is best to use standard telephone lines if conditions are met. It is better to use twisted pair cables of category 3, Category 5 or category 5 of ITU standards. The telephone lines are separated after they are entered. The first line is telephone and the first line is computer. If you want to install a telephone extension in your room, you 'd better select a good distribution box. The PC is connected to the twisted pair Cable attached to the adslmodem. (Note: Do not place the mobile phone
Next to adslmodem, because the mobile phone will automatically find the network every few minutes, the strong electromagnetic interference is enough to cause the adslmodem to be disconnected .)

2. Check your network card. If it is an ISA network card, you 'd better switch to PCI and select a good quality network card, too cheap network card may be the cause of the problem. 10 m or 10 M/M Adaptive Nic. In addition, it is also worth noting that dual NICs cause conflicts. In this case, you should unplug the network adapters connected to the LAN or other computers and use only the network adapters connected to ADSL for Internet access testing. If the fault returns to normal, check whether two NICs conflict with each other.

3. Incorrect adslmodem or Nic settings
The most common error is that the IP address of adslmodem is set incorrectly or the DNS server is set incorrectly. Because the user of ADSL virtual dialing does not need to set an IP address, it can be automatically allocated. Generally, TCP/IP gateways do not need to be set. In addition, make sure to set DNS correctly. If the operating system is Windows 9x, enter winipcfg in the DOS window to obtain the DNS address, and enter ipconfig/renew in Windows/XP, or ask the local telecommunications department.

In addition, the TCP/IP settings are the most likely to cause the inability to browse the Web page. For example, if you have not changed the settings, you can always browse normally and suddenly find that the browsing is abnormal, you can try to delete the TCP/IP protocol and then add the TCP/IP protocol again.

4. An error occurred while synchronizing the adslmodem.
Check whether your telephone line is not in good contact with the ADSL connection, or the telephone line is faulty. If you suspect that the separator is bad or the adslmodem is bad, try to directly connect the external line to the adslmodem without using the separator. If it is determined that there is no problem with the separator, ensure that the connection between the separator and adslmodem should not be too long. If it is too long, synchronization is very difficult. If the above conditions are excluded, you only need to restart adslmodem to solve the synchronization problem.

5. Dial-Up software mutual interference
There are two ways for ADSL to access the Internet: virtual dial-up and leased line access. Currently, most of the personal user's ADSL uses the former. Pppoe (Point-to-pointprotocoloverethernet Point-to-Point Protocol) has its own advantages and disadvantages. After tests on different operating systems, if the operating system is Windows XP, we recommend that you use pppoe dial-up software, which has fewer cut-off and higher stability. If you are using Windows ME or 9x, you can use the following types of virtual dialing software: enternet, winpoet, and raspppoe. Among them, enternet is a commonly used one, And enternet300 is suitable
Windows9x; enternet500 is applicable to Windows2000/XP. If you have problems with a pppoe dialing software, uninstall it and use another pppoe dialing software. Be sure not to use multiple pppoe software in the same fashion to avoid conflicts.

6. Other Software conflicts
Uninstall software that may cause disconnection. Now, some software, such as qq2000b, may lead to disconnection from the Internet. Further tests are required to determine the conditions. After uninstalling the service, many netizens found that the disconnection problem was solved, including users who used the ordinary modem163 dial-up Internet access to solve the disconnection problem, I have also received emails from my friends to solve the problem of disconnection after uninstalling QQ. If you have QQ, uninstall your OICQ first and try again on the Internet. When you find that some software is disconnected and it is normal to close it, uninstall it.

7. Improper configuration of virus attacks and firewall software
Although it is less likely to be attacked by hackers and viruses, it is not ruled out. If the virus destroys components related to ADSL, the system may also be disconnected. We recommend that you install the "Skynet firewall" or "Kingsoft network firewall", which can monitor the communication between your computer and the network in real time and warn you of inexplicable network access methods, effectively reduces the risk of attacks. If it is determined that the software is damaged or attacked by viruses, check the installed firewall, the Internet shared proxy server software, and the Internet acceleration software. After the software is stopped, then test the connection to see if the speed is back to normal.
