The LAN computer cannot be accessed, please answer the expert

It could be due to issues with firewalls, network shares, router settings, etc. Here are a few workarounds you can try:1

Check the firewall settings to make sure that computers within the LAN are allowed to communicate; 2.Check the network sharing settings to ensure that the shared folder, printer and other resources have been correctly set up with the header and turned on; 3.Check the router settings, if you use a router, you need to make sure that the settings of the intranet IP address, stupid macro allocation, and Qin Kill password are normal; 4.

Try using a different client to access, such as using a browser to access a shared folder or using a different protocol for network communication. If the above methods still do not resolve the issue, you may need to conduct a more in-depth investigation or seek professional technical support.

Under normal circumstances, users often use computers to access the LAN or the Internet to obtain more information from the outside world, and it is inevitable to encounter failure problems during use, recently there are users who have reported that the win7 system cannot access the local area network, and the win7 system local area network can not be accessed. In response to this problem, the following tells you two solutions to the inability to access the LAN.

The solution to the win7 system that cannot access the local area network:

1. Test the network

1. First click "Start" - "Run" in the win7 system, and then type the "cmd" command in the Run Pair dialog box and press Enter;

2. In the command prompt window that opens, type "ipconfig all";

3. Press the Enter key to display its network configuration, check whether the IP address, subnet mask, default gateway, and DNS server address are correct;

4. In the command prompt window, enter "command to execute, observe whether the hand-regret qing network card can ** data, when the continuous appearance of ":bytes=32time1msttl=128", it means that the network network card configuration is correct, if the continuous occurrence of "requesttimedout", it means that the network configuration is wrong or the network is faulty.

2. Procedure to check DNS resolution

1. If you can ping but can't log in to the Internet, you can use the nslookup command to test whether the DNS resolution is correct;

2. Enter " in the command prompt window and press enter, when the prompt "timedout" appears, it means that the server does not respond to the request after a certain time and a certain number of retrys, and when the prompt "noresponsefromserver" appears, it means that the DNS name server is not running on the server.

After the above troubleshooting operation, if the computer is normal, it can only mean that there is a problem with the network, and the user can install the problem and simply set it up.
