Microsoft's latest operating system windows 7 has been released for some time, the author also took the first bus of the new system. Because the author's work has a close relationship with the education network, the daily work will be maintained for the education metropolitan area network of primary and secondary schools. However, during the actual visit, I found some inconveniences in the use of windows 7, and finally set up. The above problems will be solved, and the operation steps will not be exclusive. I hope to discuss this article and the readers of it168.
First, the failure of the initial:
The author served as the network maintenance work of the primary and secondary schools in the district, because some schools have updated their internal network address to ipv6 for the convenience of future upgrade, so I often need to pass ipv6 address To visit the relevant sites. However, I recently found that some of the school internal websites that were able to log in normally have an inaccessible error message. It is found that these sites are equipped with ipv6 addresses.
Second, think about troubleshooting:
The author's own machine is t400 notebook, the installation is genuine windows 7 ultimate operating system. In order to better locate the root cause of the fault, the author through other machines, especially installed xp system The machine came to access the above site and found that there was no problem. It seems that the root cause of the failure lies in the settings of Windows 7.
(1) From the menu to configure ipv6 parameters:
Next, the author through the network search to find a solution, first from the ipv6 settings, the specific steps are as follows.
First step: Right click on the "Network" icon on the desktop and select Properties to enter the Network Sharing Center. Click to enter the local connection.
Step 2: Configure the properties of the local connection, find the internet protocol version 6 (tcp/ipv6) option, and double-click to open a new window for setting. (Figure 1)
Step 3: Fill in the ipv6 parameter information in the local network according to the rules. Because it involves sensitive information such as the network ip address segment, it will not be described in detail here. (Figure 2)
(2) From the command to configure ipv6 parameters:
After the setting is completed, the fault remains, the local computer still can not smoothly access the internal network ipv6 site, other xp system computers do not have this problem . So I used the command line again to configure the ipv6 address information. Specific steps are as follows.
Step 1: Enter cmd in the run, then right click on the command prompt and select "Run as Administrator". Open the command line window and enter netsh to configure the NIC parameters.
Step 2: Enter the following command to open our ipv6 configuration.
netsh>int
netsh>interface>ipv6
netsh>interface>ipv6>isatap
netsh>interface>ipv6>isatap>set router xxxxxxx(xxxxxx replaced with local network ipv6 routing address)
netsh>interface>ipv6>isatap>set state enabled
netsh>interface>ipv6>isatap>quit
(3) Configure ipv6 from the service:
I will try to solve the problem again after the configuration is completed. It seems that the two methods modify the ipv6 attribute to no avail. After finding the correct host file on the Internet, the fault remains. It seems that the problem does not appear in the ipv6 settings. The author continues to find the answer to the problem from the system. At this time, the author thought that there was a failure in the previous use of the windows xp system because the printer could not be shared because of the shutdown of the netshare service, so I was going to make a fuss from the "service". Enter the services.msc through the command prompt window. "Services" option window.
In this article, the author compares the difference between the windows 7 system and the windows xp system service, and finally finds that there is a service called ip helper. Through the description, the service is played as "ipv6 conversion technology. If the service is stopped, then The computer will not have the enhanced connection advantage provided by these technologies, and it happens that the corresponding ip helper service in the Windows 7 system is not in the startup state. After the service is started, the author accesses those ipv6 education websites again and there is no problem. Set the service startup mode to automatic, and the fault is completely solved after restarting the Windows 7 operating system. (Figure 3)
Third, summary:
under the Windows 7 operating system called ip helper service is responsible for ipv6 address resolution and access key, corresponding to the win xp system Ipv6 helper service, if we do not use ipv6 network related access applications, you can turn off the above services, if you want to use ipv6 network, you must open it. The actual example of this troubleshooting is because the ip helper service in windows 7 system is illegal. Iv6 site access failure caused by unexpected shutdown. I hope that you168 readers can understand the new services in the Windows 7 operating system, and can quickly locate them when they have problems.
