Is there something more simple, i just have to remove one machine.

If you delete it from the console, you have deleted it from the database.  Go to Manage->Computers, right click on the machine you want to remove and select Delete.  Have you already done this and you are noticing that something is still in the database?

I read on another post that even if i delete from the console i still have to delete from the database.
