Windows 7: The ARP entry addition failed: Access is denied

Question

I'm on Windows 7 and am trying to assign a static arp entry for my default gateway using the command:

arp -s 172.24.7.254 00-05-01-f9-28-00 172.24.1.20

But I get the following error:

The ARP entry addition failed: Access is denied.

When I don't mention my ip-address at the end, the static ip gets assigned for the virtual interface created automatically for virtualbox. I'm using an elevated prompt. I'll be grateful for suggestions. Thanks.

Answer 1

Here is what I found and it works great

arp -s : access denied. On the default gateway

Here is what I used :

delete:

netsh interface ip delete neighbors "Network card name here" "Gateway.IP.goes.here"

Add:

netsh interface ip add neighbors "Network card name here" "Gateway.IP.goes.here" "MAC-address-of-gateway-with-dash-here"

good luck

Answer 2

To set arp static in windows 7 64bit you must use netsh comand as follow

enter this command

netsh interface ipv4 add neighbors "Local Area Connection" inetaddr MAC

For Example

netsh interface ipv4 add neighbors "Local Area Connection" 192.168.0.1 00-24-01-d2-3a-bd

(If you are using a wireless rather than a LAN cable connection, use "Wireless Network Connection" instead.)

To modify routing info, you need to be an administrator.

Find the Command Prompt in your start menu, right click on it and choose "Run as administrator"
