Force ConfigMgr Compliance Baseline Evaluation on Multiple Machines with PowerShell

#Replace with name of Baseline
$BLString = "BaselineName"
 
#Replace with path to input csv (with field containing machines named Name)
$file = "c:\temp\input.csv"
 
$CountProcessed = 0
$rows = (Import-Csv $file).count
 
Import-Csv $file | ForEach-Object {
 
$ComputerName = $_."Name"
 
$CountProcessed++
$percent = (($CountProcessed/$rows)*100)
 
Cls
Write-host "$('{0:N2}' -f $percent)% complete"
 
$Online = Test-Connection -Computername $ComputerName -BufferSize 16 -Count 1 -Quiet
 
If ($Online -eq "True") {
$BLname = Get-WmiObject -ComputerName $ComputerName -Namespace root\ccm\dcm -Class SMS_DesiredConfiguration | Where-Object {$_.DisplayName -match $BLString} | Select-Object -ExpandProperty Name
$version = Get-WmiObject -ComputerName $ComputerName -Namespace root\ccm\dcm -Class SMS_DesiredConfiguration | Where-Object {$_.DisplayName -match $BLString} | Select-Object -ExpandProperty Version
$MC = [WmiClass]"\\$ComputerName\root\ccm\dcm:SMS_DesiredConfiguration"
 
$Method = "TriggerEvaluation"
$InParams = $mc.psbase.GetMethodParameters($Method)
$InParams.IsEnforced = $true
$InParams.IsMachineTarget = $false
$InParams.Name = "$BLname"
$InParams.Version = "$version"
$inparams.PSBase.properties | select Name,Value | Out-Null
$R = $MC.InvokeMethod($Method, $InParams, $null)
$R | Out-Null}
}
Write-Host "Processed" $CountProcessed "of" $rows

The input file should be formatted as follows:

Name
Machine 1
