Although it doesn???t happen very often, a bad ARP entry can cause connection issues. When this occurs, deleting the problem entry can fix the problem. And if it doesn???t, you can flush the whole thing and let Windows rebuild the cache.

In this week's TR Dojo episode, I show you how to view the ARP cahce and delete individual entries from it using the arp command and how to flush it with the netsh command.

Have you ever flush the ARP cache on a Windows machine?
