Connect two computers with a network cable and transmit data

This article focuses on the XP system.

1. Connect the two computers with a network cable. We use the most RJ45 interface network cable. Then manually set the IP addresses (for example, 172.192.1.1 subnet mask 255.255.255.0 and 172.192.1.2 subnet mask 255.255.0). Run the ping command on the computer where the IP address is 172.192.1.1 to check whether the two computers are physically connected. If it is connected, check the hardware. For example, if the network card is good or not, check whether the network cable is good.
Specific steps for setting IP addresses:
My computer-control panel-network connection-local connection right-click Properties-General-TCP/IP protocol-click Properties-General-select to use the following IP address, then fill in the IP address and subnet mask. Take A and B as an example. If you only want computer A to access the data of computer B (for example, a large number of data files are copied and transferred between computers), you only need to set B. If both A and B are set, mutual access is allowed.

2. Preparations for sharing (note that it is best to restart and take effect after the configuration is complete:
(1) Start-set-control panel-firewall-exceptions-check "file and printer sharing "! You can also disable the firewall.

(4) Open guest directly in my computer-control panel-user account. Or choose my computer> Control Panel> Administrative Tools> Computer Management> local users and groups> Users, right-click guest, and remove the check box before the account is disabled.

3. If a does not see the other Party B on the internet, check whether your working group is correct. The two parties should perform the following operations in the same working group: right-click my computer-properties-computer name to view your workgroup. If you want to modify it, click "change.

4. if "you may not have the permission to use network resources, contact the administrator of this server to check whether you have access permissions"
(1) When you click "Network Neighbor" on computer A, the possible reasons are:
① XP's built-in network firewall is not closed. Please close it. The settings are as follows:
My computer-control panel-network connection-local connection right-click Properties-advanced to see, remove the check box, don't worry about it.
(2) The reason why the above words appear when you see B in the workgroup computer of the network neighbor of:
(1) The reason is that it is on computer B.
(2) B did not turn off the firewall (its own, and later installed may all be possible)
(3) B has not enabled the Guest account
(4) choose my computer> Control Panel> Administrative Tools> Security Settings> Local Security Policy> User permission assignment> refuse to log on from the network. Check if there is any. If there is a guest, delete it.

5. Set the shared folder or drive letter, and then you can access a and transmit data from computer B.
