How to ensure stable supply lines

Win7 computer port occupancy problem solution Win7 is How to ensure stable supply linesan operating system that is still in use, but it will inevitably encounter some problems. One of the most common problems is that the port is occupied. In this case, users may encounter the problem of not being able to open an application because the port required by the application has been occupied. In this article, we will discuss the causes and solutions to the problem of Win7 computer port being occupied.I. The reason why the Win7 computer port is occupied is very simple. The reason why the Win7 computer port is occupied is that another program is already using the port. How to check which program is using the port? Here are some methods: 1. Open the command line interface and enter the following command: netstat -ano After executing this command, you will see all the running programs and the ports they use. By checking the port number and PID, you can easily find the program where the port is occupied. Two. Open Task Manager and find the program that occupies the port under the "Process" tab. 3. Open the resource monitor and find the program that occupies the port under the Network tab. II. Solution to the problem of Win7 computer port being occupied 1.Close the program that occupies the port. If you find that a program is occupying the port, the easiest way is to close the program. Usually, when you close the program, it will release the port, so you can restart the application you need. Two. Change the port of the application If you can't close the program that occupies the port, you can try to change the port of the application that needs to use the port. Generally speaking, you can find this option in the settings of the application. For example, if you are using an Apache server and find that port 80 is occupied, you can try to change it to another port (such as 8080). 3. Remotely close the program that occupies the port. If the port is occupied by the program on the remote computer, you can use the command line tool to close the program. The following is an example command: taskkill /F /IM program.Exe Please replace "program.exe" with the file name of the program you need to close. This command will force the process to close and release the ports occupied by the process. Four. Change the port occupancy policy. If you want to keep both programs available to the port, you can do it by changing the port occupancy policy. The following is an example command: netsh int ipv4 add excludedportrange protocol tcp startport 80 endport 80 This command will prohibit other programs from using port 8 0. If you want other programs to use the port, you can remove the port through the following command: netsh int ipv4 dThe command elete excludedportrange protocol tcp startport 80 endport 80 will delete the rule prohibiting the use of port 80. V. Summarize that the problem of Win7 computer port being occupied can be solved by the above methods. The easiest way is to close the program that occupies the port, but if you need the program that occupies the port to keep running, you can avoid this problem by changing the port of the application or changing the port occupancy policy. If you need to close programs on other computers, you can use the command line tool to implement it. When solving this problem, you need to be careful, because some wrong operations may cause other problems.
