Test if powershell remoting is enabled

You can use the Test-WSMan cmdlet to check whether the WinRM service is running on a remote computer.

[bool](Test-WSMan -ComputerName 'ComputerName' -ErrorAction SilentlyContinue)

function server_available?( $_server_to_act_on ) {   if ( Test-Connection -ComputerName $_server_to_act_on -Count 1 -Quiet ) {     Write-Host "`nTest-Connection: $_server_to_act_on OK" -NoNewline     if ( [bool](Test-WSMan -ComputerName $_server_to_act_on -ErrorAction SilentlyContinue) ) {       Write-Host ", Test-WSMan: $_server_to_act_on OK" -NoNewline       if ( [bool](Invoke-Command -ComputerName $_server_to_act_on -ScriptBlock {"hello from $env:COMPUTERNAME"} -ErrorAction SilentlyContinue) ) {         Write-Host ", Invoke-Command: $_server_to_act_on OK" -NoNewline         return $true       }     }  }  return $false}

Working from Straffs code above, this is my working version of how to determine if PS Remoting is working on 1 or more machines. Save the code and put it in the same folder with a file named "PCList.txt" Run the script and it will display the status as each system in the list AND produce a new report each time you run it in .CSV format directly clickable into excel. Put one machine per line in the PCList.txt file. You must have local admin access to the remote machines for this to work, always "Run As Administrator"
