All the clients in my wireless network send continuously arp requests to a
host that doesn't exist (I've checked its absence with
nmap -PN [IP]).
The clients use windows 7 and windows xp (here the requests are sent with less frequency).What does it mean?
I think that this behavior is the reason of my network congestion... but what can i be sure?! Is there a way to check which process send the arp request?
