Windows server display current TCP connections

There are several ways you can display the current TCP connections on a Windows Server. Here are a few options you can try:

1. Use the "netstat" command: The "netstat" command is a command-line utility that displays active TCP connections, as well as a number of other network statistics. To display active TCP connections, use the following command:

netstat -ano

This will display a list of active TCP connections, along with the local and remote address and port number for each connection, the process ID of the process that owns the connection, and the connection status. The "-a" option shows all connections, including those in the listening state, and the "-n" option displays the addresses and port numbers in numerical form rather than trying to resolve them to hostnames. The "-o" option displays the process ID for each connection.

2. Use the "Task Manager": You can also use the Task Manager to view current TCP connections. To do this, follow these steps:

• Press "Ctrl+Alt+Delete" and select "Task Manager" from the menu.
• Click the "Details" tab.
• Scroll down and find the "PID" column.
• Right-click the "PID" column and select "Select Columns".
• Check the "TCP Connection State" box and click "OK".

This will add a new "TCP Connection State" column to the Task Manager, which displays the status of each process's TCP connections.

3. Use the "Resource Monitor": You can also use the Resource Monitor to view current TCP connections. To do this, follow these steps:

• Press "Win+R" and type "resmon" into the Run dialog.
• Click the "Network" tab.
• Click the "TCP Connections" button in the toolbar.

This will open a new window that displays a list of current TCP connections, along with the local and remote address and port number, the process ID of the process that owns the connection, and the connection status.

It is important to note that these methods will only show active TCP connections. If you want to see closed or terminated connections, you may need to use additional tools or techniques.
