Hi Guys,

I am filtering packets using wireshark and i was checking every user on the network what traffic he causes.

Half the user are all the time sending a broadcast ARP Request - Who is 172.16.80.55

This user does not exist.... and no one on the network has that IP (although it is DHCP) it has been a long time since someone took that IP.

What could be the problem?????

Thanks

That is because you probably do not have a local DNS server resolving names on your network. It is normal.

Ok found the problem. Apperently once there was a printer which is no longer in use with that IP which was still installed on many users. That was the problem. Removed Printer from user and no more broadcast for that IP.

Thanks Mate.
