getting quick arp request

[seb]

Hi Ben,

I am indeed using XP SP2.
I have checked on the event viewer and I have not seen the event 4226.

Besides I also run on the same PC angry Ip scanner 2.21. Checking using
ethereal the arp request are all dispatched quit quickly (see my mail
above).

Thanks for the advice anyway.
Sebastien.
