Reply To: Work an Array in Batches of 5

You could simply pass your entire array to Invoke-Command without using New-PSSession first. It will handle the queue behind the scenes for you. For example, instead of this:

invoke-command -session $s -scriptblock {$net = new-object -ComObject WScript.Network}
invoke-command -session $s -scriptblock {$drive = ls function:[g-z]: -n | ?{ !(test-path $_) } | select -first 1}
invoke-command -session $s -scriptblock {$net.MapNetworkDrive($drive, "\\Mapped Network Location\Visio 2010", $false, "Domain\Username", "Password")}
invoke-command -session $s -scriptblock {set-location $drive}
invoke-command -session $s -scriptblock {.\setup.exe}

You could combine those separate calls to invoke-command into a single, multi-statement script block that is called against many computers:

Invoke-Command -ComputerName $hugeComputerArray -ScriptBlock {
    $net = New-Object -ComObject WScript.Network
    $drive = ls function:[g-z]: -n | ?{ !(Test-Path $_) } | select -first 1
    $net.MapNetworkDrive($drive, "\\Mapped Network Location\Visio 2010", $false, "Domain\Username", "Password")
    Set-Location $drive
    .\setup.exe
}
