PowerShell Remoting Deep Dive

Remoting lets you run commands on remote computers as if you were sitting at them.

How It Works

PowerShell remoting uses WinRM. Commands are serialized to XML, sent over HTTP (port 5985) or HTTPS (port 5986), executed remotely, and results returned.

Setup

Enable-PSRemoting -Force
Get-Service WinRM
Test-WSMan -ComputerName Server01

One-to-Many

$servers = Get-Content servers.txt
Invoke-Command -ComputerName $servers -ScriptBlock { Get-PSDrive C }

Sessions

$session = New-PSSession -ComputerName Server01
Invoke-Command -Session $session -ScriptBlock { Get-Service }
Remove-PSSession $session
