Discover all active computers in a domain


I'm doing a software deployment to our desktops and want to find out which computers are active. Ideally I would like to produce a list that details all computers in AD that have been accessed withing say 60 days.

Is this possible or is there a tool that will do this for me?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Powershell will do the job for you.  Run the following string (on a machine with the AD Powershell component installed)

$60days = (get-date).adddays(-60)
Get-ADComputer -SearchBase "DC=YourDomain,DC=co,DC=uk" -filter {lastlogondate -le $60days -AND passwordlastset -le $60days -Properties lastlogondate, passwordlastset | Select-Object name, lastlogondate, passwordlastset, distinguishedName | Out-File -filepath "filename.txt"

DSQUERY will do the trick easily and in one command.

The above command should get a list of all computers that have been inactive for the last 9 weeks (63 days).
As Lee mentioned use DSQUERY command to get the data.

dsquery computer -inactive 8 >> C:\Inactive_Computers.txt
