With this little Powershell Script you can run Powershell Commands on multiple Remotehosts even if those are not in an Active Directory.
# Config
$Servers = @("Server01", Server02)
$Cred = Get-Credential # Add Credentials for all Servers (Domain or non-Domain)
# Run Command (for example Get-Service | Where-Object {$_.Name -eq "BITS"}
foreach ($Server in $Servers) {
Invoke-Command -ComputerName $Server -Credential $Cred {Get-Service | Where-Object {$_.Name -eq "BITS"}}
}
Important:
You have to enable Powershell Remoting on the Remotehost with Enable-PSRemoting
