Symptom:Run cmd directly under win7 and run arp-d * or arp-s. the following error message is displayed: ARP entry deletion failed: the operation needs to be upgraded. ARP entry addition failed: Access denied. Or an error occurred while adding ARP entries: the requested operation must be upgraded. (The ARP entry addition failed: Access is denied .) Solution:Run arp-d * as an administrator. Go to the windows \ system32 folder and find cmd.exe. Right-click "Run as administrator" to open the cmd program and run the arp-d command. However, you still cannot run arp-s for static mac binding. You need to use the netsh command. Procedure:1. Run netsh I show in to find the idx Number of the network adapter in use 2, and then run netsh-c I add neighbors 11 192.168.1.1 00-21-27-bc-89-48 to bind the network adapter, here 11 is the idx number. Using arp-d on Windows 7 and Vista does not completely delete the binding. netsh-c "I" delete neighbors IDX is required (IDX is changed to the corresponding number) to delete the MAC address. The arp-s command bound to the MAC address also produces the same error in Vista.

Run the arp-a command to view the physical address of the MAC Nic of the gateway. 2. Run the netsh I show in command to view the idx number of the local connection. 3. Run netsh-c "I" add bind the idx "gateway IP" "Gateway mac" command locally connected to neighbors. 4. Use arp-a to view the result.
