Computers being deleted the next day after joining DC

Hi,

We are having a problem DC (Build Version:10.0.91) where computers are being deleted once the client has been installed on the machine.

So when we build a computer we get this message in our admin mailbox.

As you can see from this email the machine was built on the 27/06/2017 at 3:23 and as part of the build process the DC agent gets deployed.

The next day we get this message in our admin email account.

This is only deleting the computer from DC as the computer object in AD is still there.

So have setup the DC to delete computers after 2 months.

so as you can see this, a computer shouldn't be deleted 1 day after it was built. We don't get any emails saying that the computer hasn't been in contact.

Any idea what could be causing this issue.
