A Windows XP-based computer sends many ARP broadcast requests when the ARP cache entry for the peer expires during a large file transfer (840164)


The information in this article applies to:

  • Microsoft Windows XP Professional
  • Microsoft Windows XP Home Edition

SYMPTOMS

A Microsoft Windows XP-based computer may send many Address Resolution Protocol (ARP) broadcast requests when the ARP cache entry for the peer expires during a large file transfer.

CAUSE

This problem typically occurs when the Windows XP-based computer has a firewall program installed that blocks ARP replies. For example, if you communicate or if you copy files between a Windows XP-based computer and a destination computer and you turn on the ARP blocking feature, the Windows XP-based computer submits an ARP request to the destination computer when the ARP cache expires on the Windows XP-based computer. In this scenario, the ARP reply from the destination computer is blocked by the firewall. Therefore, Windows XP begins to broadcast many ARP requests.
