Hi -
In my Vista machine, when I try to add a static ARP entry, it fails with
"The ARP entry addition failed: 5". I did use the arp command in a "Run as
Administrator" command prompt.

I have two interfaces on my machine: Ethernet and Wireless. Both are
connected to the same subnet. I have assigned non-conflicting IP addresses to
the interfaces manually (192.168.20.14/24 and 192.168.20.4/24 respectively).
I use the following commands:

arp -s 192.168.20.12 00-09-xx-xx-xx-xx 192.168.20.14

Fails with "The ARP entry addition failed: 5".

arp -s 192.168.20.12 00-09-xx-xx-xx-xx 192.168.20.4



Successful.


BTW, Dynamic addition of the ARP entry in 192.168.20.14 interface is no
problem.


Appreciate any help.

Thanks,
Anand
