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
