Method 1: Check Ports with Command Prompt

First and foremost, you should try command prompt to check ports in Windows Server. The netstat command provides a quick overview of active ports. Here’s what you should do:

1. Open Command Prompt as Administrator.
2. Run the following command:
   netstat -ano
3. Once you hit enter after typing the aforementioned command, it lists all active connections, local addresses, and ports in use.
4. Finally, note the PID (Process ID) to identify which process is using a port.

Method 2: Use PowerShell to Verify Specific Ports

While command prompt is always handy to check ports, PowerShell is more precise when you want to check individual ports.

• To check if port 443 is open, type the following command and hit enter:
  Test-NetConnection -ComputerName localhost -Port 443
• To check if port 8080 is open, type the following command and hit enter:
  Test-NetConnection -ComputerName localhost -Port 8080

This command returns details such as TcpTestSucceeded, which confirms if the port is responding.

Method 3: Check Ports via Resource Monitor

For a graphical option, Resource Monitor provides an easy view. All you need to do is follow the steps given below:

1. First, press Ctrl + Shift + Esc to open Task Manager.
2. Then, go to Performance > Open Resource Monitor.
3. Now, under the Network tab, expand Listening Ports.
4. Lastly, you’ll see all open ports, their associated processes, and the protocol.

Summing up

Windows Server gives you several ways to check port usage, from Command Prompt’s netstat to PowerShell’s Test-NetConnection and the Resource Monitor GUI. Keeping track of ports is vital for service uptime, troubleshooting, and security.
