Deleted Machines Keep Reappearing in the SMS Database

I recently installed a bunch of new workstations and removed the old ones from the database and the network. The next day, they're back in the database. I removed them again - next day, they're back. Can someone suggest a way to permanently get these out of the database?

If you are running Network Discovery, are you using DHCP discovery? If so, the client systems may have leases that are still valid. If so, DHCP reports them as valid resources, even if they are no longer active on the network.

If you’re not using DHCP Discovery then look to what Discovery method discovered the client.
