PowerShell Commands on Remote Computers

PowerShell Remoting allows you to run individual PowerShell commands or access full PowerShell sessions on remote Windows systems. It’s similar to SSH for accessing remote terminals on other operating systems.
PowerShell is locked-down by default, so you’ll have to enable PowerShell Remoting before using it.


On the computer you want to access remotely, open a PowerShell window as Administrator – right click the PowerShell shortcut and select Run as Administrator.


Enable-PSRemoting -Force

This command starts the WinRM service, sets it to start automatically with your system, and creates a firewall rule that allows incoming connections. The -Force part of the command tells PowerShell to perform these actions without prompting you for each step.


Testing the Connection.

On the computer you want to access the remote system from, use the Test-WsMan cmdlet to test your configuration. This command tests whether the WinRM service is running on the remote computer – if it completes successfully, you’ll know that WinRM is enabled and the computers can communicate with each other. Use the following cmdlet, replacing COMPUTER with the name of your remote computer:

Test-WsMan COMPUTER

Executing a Remote CommandTo run a command on the remote system, use the Invoke-Command cmdlet. The syntax of the command is as follows:

Invoke-Command -ComputerName COMPUTER -ScriptBlock { COMMAND } -credential USERNAME

COMPUTER represents the computer’s name, COMMAND is the command you want to run, and USERNAME is the username you want to run the command as on the remote computer. You’ll be prompted to enter a password for the username.

Use the Enter-PSSession cmdlet to start a remote PowerShell session, where you can run multiple commands, instead of running a single command:


Enter-PSSession -ComputerName COMPUTER -Credential USER
