List Computer Object in an Active Directory OU using PowerShell

How to get a list of computer objects in an active directory OU ( tested against Windows 2016 Active Directory )

A quick PowerShell script using Get-ADComputer  command, a wild card filter and a search base pointing to a specific OU


First import modules for active directory in powershell


Copy and edit the script below:

## cmd

## dsquery computer -name servername (server name in the OU to get the OU path)

#Example lists domain controller in

#Export list of names to CSV

Get-ADComputer -Filter * -SearchBase “OU=Domain Controllers,DC=test,DC=com” | Select Name | export-csv C:\temp\DCs.csv


( Like the post click and advert of interest to give us support)

Get a list of inactive computers which have not logged on to the domain in the last 12 weeks

# Inactive computers ( this will include systems not regularly used)

# Launch command prompt as administrator and run the following commands

Dsquery computer -inactive 12 -limit 500

# Lists computers inactive for over 12 weeks and returns a limit of 500 results

Dsquery computer -inactive 12 -limit 500 | dsmod computer -disabled

# Lists computers inactive for over 12 weeks and returns a limit of 500 results and disables the computer accounts


# Similar command can be done for users.


Disable inactive computers in AD

I would be tempted to run it manually in two parts.. that sounds a little cautious I know..

From your DC you can run

CMD ( as admin )
dsquery computer -inactive 8
(this lists the inactive computers- this list can include serveres!!!)

This will list the computers which have been inactive for 8 weeks or more.

Then you can choose to manually select the highlighted computers (from the query) in AD right click disable.
Or run    dsquery computer -inactive 8 | DSMOD computer -disabled yes

This will error if there is nothing to update “dsquery computer -inactive 8 | DSMOD computer -disabled yes”

I would not schedule this to run automatically.. Just in case it bins a server.. even though servers should never been offline for 8 weeks
