Whenever you use Invoke-Command to remotely execute code, you will notice that PowerShell automatically adds the column PSComputerName to your results. That's great because when you run Invoke-Command against more than one computer, you want to still know which computer returned particular information.
Invoke-Command { Get-Service } -ComputerName PC1, PC2, PC3
If this does not work for you, make sure you enabled and configured PowerShell Remoting correctly first.
The problem with PSComputerName is: it disappears whenever you use Select-Object to tailor the resulting columns:
Invoke-Command { Get-Service } -ComputerName PC1, PC2, PC3 | Select-Object PSComputerName, Name, Status
To work around this problem, define a hash table to add the sender’s name. As a side effect, you now can also give the column a better name:
$pcname = @{ Name = 'Machine' Expression = { $_.PSComputerName } } Invoke-Command { Get-Service } -ComputerName PC1, PC2, PC3 | Select-Object $pcname, Name, Status
