Adding a static arp entry in Windows 7

Following up on a previous article where I explained how to add a static ARP entry on Linux, trying to do the same on Windows 7 you would get an error message Access denied. This is how we would do it on Windows 7:

If, for example, we are using a network connection, first we execute ipconfig on a cmd box to list the interface name:

We see that our Wireless network is named Wireless Network Connection, also that the gateway has the IP address 10.43.1.1. From a cmd command prompt we list the current arp table:

 We have identified the mac address as 00-30-48-99-de-97. Now, from an elevated cmd prompt we execute the following netsh command to add the static entry:

netsh.exe interface ipv4 add neighbors "Wireless Network Connection" 10.43.1.1 00-30-48-99-de-97

That's all.
