We had a similar problem on an NT server. ARP problems normally have to do with bad cables, NICīs and/or Hubs/Switches. We changed our switch and cables without success. We then changed the NIC to a new one, same brand and model: big mistake, no success. Finally changed to a different brand/model of NIC and problem was solved. Just wanted to share our experience.
