ADUC: Clear 'dead' computers

I use powershell to query for users / computers that haven't been seen for a while, and then I take the list and manually remove the ones I know for certain are gone.

PS would be an excellent tool for this - I'll have to see about building one out unless you care to share. I know I have stall entries.

I don't have the scripts with me (old job) but the command syntax is along these lines.

Get-ADComputer -identity compname -Properties * | FT Name, LastLogonDate

To query the entire domain:

Get-ADComputer -Filter * -Properties * | FT Name, LastLogonDate -Autosize

momurda

Get-ADComputer -filter * -properties * | Sort LastLogonDate -Descending | Select Name, LastLogonDate
will sort by date, giving you lonely pcs at bottom of terminal.

Another way to do it

Get-ADComputer -Filter {PasswordLastSet -le $lastSetdate} -Properties passwordLastSet -ResultSetSize $null | FT samaccountname,PasswordLastSet

Another example taken from another script:

import-module activedirectory  
$domain = "domain.mydom.com"  
$DaysInactive = 90  
$time = (Get-Date).Adddays(-($DaysInactive)) 
  
# Get all AD computers with lastLogonTimestamp less than our time 
Get-ADComputer -Filter {LastLogonTimeStamp -lt $time} -Properties LastLogonTimeStamp | 
  
# Output hostname and lastLogonTimestamp into CSV 
select-object Name,@{Name="Stamp"; Expression={[DateTime]::FromFileTime($_.lastLogonTimestamp)}} | export-csv OLD_Computer.csv -notypeinformation
