So could tombstone > records be causing this?I personally think the 'tombstone' is a bit of a red herring. If you re-install a machine with the same name, ip etc, even if it looks like the same machine to you, to Windows it is a different machine and that new machine will not be able to alter any records for the old machine.> If so is there a workaround?You could try deleting the old records and let your new machine create new ones.

Yes, I tried that, the A record in the forward zone and the PTR record in the reverse zone for the old machine (LION-X99) was deleted, but still getting these errors for the new machine (LION). Or did you mean deleting the tombstoned records? BTW it created the A record in the forward zone automatically when I joined the new machine to the domain. It's just the PTR record that's not being allowed to be created automatically. Roy
