PowerShell Cmdlet Spotlight: Enable-PSRemoting

Welcome back to Wahmans PowerShell Blog! Today, we are diving into a fundamental cmdlet that serves as a building block for anyone working with PowerShell remoting — Enable-PSRemoting.

What is Enable-PSRemoting?

According to Microsoft, Enable-PSRemoting “Configures the computer to receive remote commands.” In simpler terms, this cmdlet prepares your machine to allow incoming PowerShell remote sessions, which is crucial for remote management, automation, and configuration of systems.

Why Use Enable-PSRemoting?

Remote PowerShell sessions allow administrators to execute scripts or commands on remote systems as if they were sitting in front of them. Whether you’re managing a single system or an enterprise fleet of servers, remoting is a powerful tool in your automation toolbox.

Let’s Dive Into Some Examples

Example 1: Basic Usage (Beginner)

Enable-PSRemoting -Force

This is the most straightforward and popular way to enable PSRemoting. The -Force parameter suppresses confirmation prompts, making it suitable for automation scenarios like scripts or deployment tasks.

Example 2: Enable Remoting on Multiple Computers Using a Loop (Intermediate)

$computers = @("Server01", "Server02", "Server03")
foreach ($computer in $computers) {
    Invoke-Command -ComputerName $computer -ScriptBlock { Enable-PSRemoting -Force } -Credential (Get-Credential)
}

This script enables remoting on multiple servers by invoking the cmdlet remotely using Invoke-Command. Useful for managing clusters or enterprise environments.

Example 3: Configure a Non-Domain Machine for Remoting (Advanced Beginner)

Enable-PSRemoting -SkipNetworkProfileCheck -Force

By default, Enable-PSRemoting does not allow remoting on public networks. If your machine is not domain-joined and only connected to a public network, use the -SkipNetworkProfileCheck flag with caution.

Example 4: Enable Remoting and Modify the Trusted Hosts List (Advanced)

Enable-PSRemoting -Force
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "192.168.1.1,192.168.1.2"

When dealing with workgroup computers or systems not in the same domain, modifying the trusted hosts list is essential. This configuration allows your local system to trust and communicate with specific remote hosts.

Wrapping Up

Enable-PSRemoting is a foundational cmdlet that opens the door to some powerful automation and remote management capabilities in PowerShell. Whether you’re just starting or managing hundreds of systems, understanding this cmdlet is crucial for your PowerShell journey.
