How do I find out which program and process ID accesses a given IP address in Windows?

As an IT admin, you may find yourself in a situation where you need to figure out which program and process ID is accessing a given IP address on your Windows system. This can be a difficult task, especially if you are not familiar with the Windows operating system. However, there are a few methods you can use to help you identify the program and process ID that is accessing the IP address.

The first method you can use is to use the Task Manager utility. To open the Task Manager, you can press the Ctrl + Alt + Delete keys simultaneously, then select Task Manager from the menu that appears. Once the Task Manager has opened, switch to the Details tab, and then look for the process ID (PID) that is associated with the IP address. You can also right-click on the process and select “Go to Details” to get more information about the program that is associated with the process.

The second method you can use is to use the command line utility called netstat. To use this utility, open a command prompt window and type “netstat -anb”. This command will show a list of all active connections on your system. Look for the IP address you are interested in and the associated port number. The process ID associated with the IP address will be listed in the “PID” column.

The third method you can use is to use the Resource Monitor utility. To open the Resource Monitor, press the Windows + R keys simultaneously, type “resmon.exe” in the Run dialog, and then press Enter. Once the Resource Monitor has opened, switch to the Network tab and look for the process ID associated with the IP address you are interested in.

Using any of these methods should help you identify the program and process ID that is accessing a given IP address on your Windows system. Once you have identified the program and process ID that is accessing the IP address, you can then take appropriate action to stop the program from accessing the IP address or make changes to the program or process to ensure that it is not accessing the IP address.
