Ask any young buck how to solve a problem and PowerShell will be the solution. Talk to the old guard and they will have a specialty tool. Both sides have valid points. PowerShell has near universal support and common parameters. Single use tools often have advanced features that are easier to access and don’t need to be reinvented.
I see this conversation/argument play out every day online. Lately, this discussion started with questions on stale object cleanup in Active Directory. I looked over my old answer to this problem and saw that it needed some work.
To piss off both sides, I combined both approaches by using PowerShell with the OldCmp AD query tool. The solution, to me, is easier to use. It leverages the plug and play mentality of PowerShell with the robustness of a specialty tool. Best of all, you can have this running in just a few minutes for both users and computers!
Combining PowerShell and OldCmp
This script is designed to run as a regular monthly scheduled task. Each time it runs, it will copy the previous report to an Old Reports sub folder. If any objects in the stale OU are enabled, they will be moved and any remaining disabled objects will be deleted. The script will then run the oldcmp tool and email the cleanup report.
- Create a folder at C:\Scripts and name it DisableStaleComputers . Save the script to this folder.
- Download OldCmp and save it to the DisableStaleComputers folder.
- Create a sub folder named Old Reports in the DisableStaleComputers folder.
- At the top of the script, customize the script variables for your environment. Before running this script, generate a report by running .\OldCmp.exe -report -age 270 -llts. You will also need to remove the hash symbol near the end of the OldCmp command (line 25)
#OU where stale objects will be moved.
$StaleOU = "OU=Stale Computers,OU=Stale Objects,DC=TEST,DC=local"
#OU where re-enabled objects will be moved.
$SafeOU = "OU=Computers,OU=Sites,DC=TEST,DC=local"
$SmtpServer = "SERVER"
$SmtpFrom = "FROM"
$SmtpTo = "TO"
#Move Old Report into Old Report Folder
Get-Item *.htm | Move-Item -Destination '.\Old Reports\'
#Move Enabled Object to OU
$Unstale = Get-ADComputer -Filter * -SearchBase $StaleOU | where Enabled -EQ $true
$Unstale | Move-ADObject -TargetPath $SafeOU
#Clean Out Stale objects OU
Get-ADComputer -Filter * -SearchBase $StaleOU | Remove-ADObject -Recursive -Confirm:$False
#Disable stale objects
.\OldCmp.exe -disable -age 270 -llts -newparent $StaleOU -nodc -sort cn -excldn 'BOARD;Server' #-unsafe -forreal
Send-MailMessage -Attachments *.htm -SmtpServer $SmtpServer -From $SmtpFrom -To $SmtpTo -Subject "Stale Computers Report" -body "Attached are the objects that have been marked as stale and moved into the stale objects OU."
To cleanup stale users, repeat the steps above and add a -users parameter to the .\OldCmp line in your new saved script. Be sure to change Get-ADComputer to Get-ADUser in the script as well.
You can view all parameters and examples here for the OldCmp tool. The only thing that I have left to figure out is if I’m still a young buck or a member of the old guard. 🙂
Ran the tool as per notes – warning, if you have anything in that OIU already, it will delete it on first run (even with hash in place)
