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

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

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.)
