Windows 2000/2003 Print servers making large number of ARP broadcasts...why?

Last Modified: 2010-04-18
I have been doing random sniffer/packet scans of my network to check things out over the past few days, using Ethereal.

There seems to be a constant flood (80% of total packets) of ARP traffic for some reason, both during business hours and off.

What's odd is that the ARP traffic is coming from my two Windows 200/2003 print servers. They are broadcasting ARP requests constantly trying to verify IPs on the same subnet as the printer server.

My network uses DNS, no WINS. "Netbios over TCP" is disabled on the servers. Hosts file, Lmhosts are empty.

Does anyone know why my print servers are making these constant broadcasts? This is worrying me......
