The ARP entry addition failed: Access is denied.
Today I was trying to add an ARP entry on my latptop to the default gateway of my network. It gave me following error:
“The ARP entry addition failed: Access is denied.”
I also tried by opening command prompt prompt with “run as administrator” option but this problem continued to show up.
After a little research I found that the windows gives this error when someone tries to put arp entry for Default Gateway of the system.
So I simply removed my default gateway entry in:
Afterwards I disabled and re-enabled my network card and tried to enter arp entry again.
arp -s 192.168.10.1 aa-bb-cc-dd-ee-ff
Bingo! This time it was successful. Afterwards I simply inserted my gateway entry “192.168.10.1” back in the properties
The system started working 🙂
