How check netstat in windows

If you want to monitor active connections, listening ports, or troubleshoot networking issues on Windows, netstat is your go-to tool. Here’s how to use it effectively via Command Prompt.

Step 1: Open Command Prompt as Administrator

Hit Win + S, type cmd, then right-click on “Command Prompt” and choose Run as administrator. This gives you full access to all netstat functionalities.

Step 2: Run Basic Netstat Command

To see all active connections and listening ports:

netstat

This will display:

• Protocol (TCP or UDP)

• Local address and port

• Foreign address and port

• Connection state (e.g., ESTABLISHED, LISTENING)

Step 3: Use Netstat with Parameters

Want more details? Add flags to customize output.

Show all active and listening connections with process IDs:

netstat -ano

This is especially useful if you want to identify which PID (Process ID) is using a specific port.

Combine with tasklist to find the process name:

tasklist | findstr [PID]

Example:

tasklist | findstr 1234

See only listening ports:

netstat -an | findstr LISTENING

Filter for specific port (e.g., port 80):

netstat -an |
