Removing old computer accounts across several domains

Hello all,

I need to either find a tool (such as ADtidy or oldcomp) or write a powershell script that will allow me to identify and then delete (as required) computer accounts that have not logged into the domain over a given time period.  The real challenge is I need to be able to check across several domains.

I'm using the following powershell script as a basis but this only references one domain:
(Thanks Matt Vogt)

$time = Read-host
$time = get-date ($time) $date = get-date ($time) -UFormat %d.%m.%y
Get-ADComputer -Filter {LastLogonTimeStamp -lt $time} -Properties LastLogonTimeStamp
select-object Name,@{Name="Stamp"; Expression={[DateTime]::FromFileTime($_.lastLogonTimestamp)}} | export-csv .all_old_computers_timestamps

My scripting skills are very rusty so need some help!

Good luck!
