That wasn't a very helpful error message from arp! :) in WinError.h, error
87 is ERROR_INVALID_PARAMETER - which is pretty misleading (or wrong) for
this situation.

I believe you're actually getting the error because you don't have the
administrative privileges required to purge the cache. Right-click the
Command Prompt icon in Start Menu, and choose "Run as Administrator". Give
your consent to the UAC prompt. Now you have an Administrator command
Prompt - in the title bar, it will actually say "Administrator: Command
Prompt" (as opposed to just plain "Command Prompt").

Now run "arp -d" again. This time it should work.

I usually leave an Administrative prompt running in the background, so I can
quickly run utilities with elevation.

Hope it helps,
