Introduction The Get-NetTCPConnection cmdlet in PowerShell is a powerful tool that allows Windows users to retrieve information about active TCP connections on their system. This article aims to provide a comprehensive guide on how to use Get-NetTCPConnection effectively in the Windows environment. By understanding and utilizing this cmdlet, users can gain valuable insights into network connections, troubleshoot issues, and optimize their system's performance.

Examples:

1. Retrieving all active TCP connections: To retrieve a list of all active TCP connections on your Windows system, you can use the following command in PowerShell:

Get-NetTCPConnection

This command will display a table with detailed information about each connection, including the local and remote addresses, state, and process ID.

2. Filtering connections by state: If you want to filter the connections based on their state, you can use the -State parameter. For example, to retrieve only the established connections, you can run the following command:

Get-NetTCPConnection -State Established

This command will display a list of all TCP connections that are in the established state.

3. Filtering connections by process ID: To retrieve connections associated with a specific process ID, you can use the -OwningProcess parameter. For example, to find all TCP connections owned by process ID 1234, you can run the following command:

Get-NetTCPConnection -OwningProcess 1234

This command will display a list of TCP connections associated with the specified process ID.
