I would like to know in which case the arp cache needs to be manually deleted on computers.
in some MS OS version, the command is arp -d, and in some others susch as Windows 7, NETSH ...... is used.
what would clearing the cache help in troubleshooting a computer, assuming that no hardware in the network has been changed?

thanks

That would be a good and quick practice while trying to resolve connection problems regardless of the operating systems in use:

- After or during ARP-pollution virus attacks
- Power blackouts or spikes when the network switches might be in strange states
- When a particular computer seems to be able to ping only some of the hosts in the LAN
