When I enter the command line arp -d *
at an instance of cmd.exe, I get
The ARP entry deletion failed: The parameter is incorrect
I can delete individual entries fine, e.g. arp -d 192.168.1.1
I also have Cygwin and Git Bash installed, so I thought maybe the *
was getting expanded like in a Unix shell, but it doesn't appear so, as echo *
from cmd.exe results in a simple *
output. I have also tried escaping the asterisk and enclosing it in quotes with arp -d "*"
and arp -d ^*
. Both result in the same error.
I do have two NICs on this machine, an internal and a USB, but I get the same error when I unplug the USB NIC.
The account I am running from is an administrator, and I have also tried right-clicking cmd.exe and selecting "Run as Administrator."
1Same result confirmed on Win10 Pro. – mt025 – 2016-09-20T18:58:49.783
Hm, is this something I just haven't noticed yet on Win7? The '*' wildcard is supposed to be supported according to the
arp -help
documentation, and it used to work in XP... – Sam Skuce – 2016-09-20T19:01:03.7771This happened to me on two HP machines that I recently restored to the original factory settings. All of the other machines of the same model had no issues with this command. This was using Windows 10. – kojow7 – 2018-10-23T20:03:44.317
