Win7 ARP command Run failure resolution

Run cmd directly, run arp-d *, arp-s The following error message appears:

ARP Entry deletion failed: The requested operation requires elevation.

ARP entry added failed: Access denied. or hint: theARP entry failed to add : The requested operation requires elevation.
(English version hint: the ARP entry addition Failed:access is denied. ）

How to solve it?
Run arp-d * need to run as administrator, go to the Windows\System32 folder to find Cmd.exe, right-click "Run as Administrator", so open the CMD program can run the arp-d command. However, it is still not possible to run Arp-s for static Mac binding, presumably Win7 disable this command, need to use the Netsh command.

The specific approach is:

1. Run First: Netsh i i show in Find the network card in use IDX number

2, then run: netsh-c i i add neighbors one 192.168.1.1 00-21-27-bc-89-48 can be bound, here 11 is the IDX number.

Using arp-d on Win7 and Vista does not completely remove bindings
Must use
Netsh-c "I i" delete neighbors idx (idx changed to corresponding number)
To remove the MAC address bindings

The same error will occur in Vista!

Solutions

0. Use the arp-a command to view the physical address of the Gateway's MAC network card

1. Use the netsh i i show in command to view the IDX number of a local connection

2. Use netsh-c "I i" add neighbors local connection idx "Gateway IP" "Gateway Mac" command binding

3. Use Arp-a to view results
