Is it possible to turn off auto-discovery? After my PRTG installation, I run the auto-discovery. The auto-discovery works fine and finds all devices. So after the auto-discovery was finished, I deleted all the client workstations in PRTG, because I won`t monitor them. Yesterday the auto-discovery started automatically (I found no option to disable the auto-discovery) and all client workstations that I deleted are back. I don`t want to see all the client workstations. How can I configure PRTG so that these devices are not added?
