I have a auto-discovery group enabled that keeps looking for new devices in a class c network. The auto-discovery group is using dns and should skip known devices/ip's according to the settings but somehow multiple entries of the same devices popup.
Maybe it's a coincidence but only Windows 10 devices create duplicate entries, server editions or Linux devices never show up as a duplicate.
I've noticed that sometimes the name of the client is discovered with all uppercase letters and another time just with the first letter capital but even with these variations in naming I've currently got duplicates.
How can i prevent the creation of duplicate entries? PRTG is version 188.8.131.5230
