Reboot and go immediately to Administer mode and repeat what Andrew posted substituting arp-d as C:\> arp -d*
Notice the spacing between > and a and also between p and -
Alternatively, use the command prompt below while in Administrator mode and enter the following and hit OK and reboot immediately when done
C:\>netsh interface ip delete arpcache

This isn't an admin rights issue. I tried runas admin and even tried as
the actual administrator user, and still get the error 87. Any new ideas
on how to clear the Arp cache in Vista?
Thanks,
James

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,
