Yield to the OS

Hi

If I have a while loop that simply holds execution until a command has
completed how do I stop it frying the processor?

What I am actually doing is mapping a network drive and I want to ensure
this has finished before continuing e.g.

$net = $(New-Object -Com WScript.Network)
ForEach ($hst in $hstLst)
{
$pingStatus = gwmi Win32_PingStatus -Filter "Address='$Hst'"
If($pingStatus.StatusCode -eq 0)
{
$path = "\\" + $hst + "\C$\Temp"
$path
$net.MapNetworkDrive("Z:", $path)
While(![System.IO.Directory]::Exists("Z:")){}
write-host -ForegroundColor GREEN $hst
$(get-acl z.access
$net.RemoveNetworkDrive("Z:", $true)
While([System.IO.Directory]::Exists("Z:")){}
}
Else
{
write-host -ForegroundColor RED $Hst" - UNAVAILABLE"
}
}

How can I yield to the OS during the while loop?

Thanks for any help you can offer

start-sleep ?

Try a start-sleep.

Like
While(![System.IO.Directory]::Exists("Z:")){start-sleep 5}
