SYMPTOMS
When you copy a large file from a network file share on a Microsoft Windows 2000 Service Pack 4 (SP4)-based computer, Windows 2000 may broadcast too many Address Resolution Protocol (ARP) packets over the network. This issue causes overall network performance levels to decrease.



CAUSE
This issue may occur if the computer that is sending the ARP packets does not receive an immediate reply. This issue occurs when the ARP cache entry expires during the file-copy operation.
