$machines = Get-Content "c:\temp\machines.txt"
del c:\temp\not-in-ad.txt
foreach ($machine in $machines) {

#query AD to see if this machine exists. If not, write to a file

#uses the quest AD cmdlets..Probably need to change to built in AD cmdlets in POSH 2.0

$this = Get-QADComputer -Identity "contoso\$machine$" -ErrorVariable $Error_get_computer

if ($this -ne $null){
  Write-Host "$machine is in AD"
  }
	
else {
	Write-Host "$machine is NOT in AD" 
	Out-File -InputObject "$machine" -Append -FilePath "c:\temp\not-in-ad.txt" -Encoding ASCII}
