jstinehelfer :

Hello, My name is John and I am an expert with JustAnswer.com. Thank you so much for using our services. I do believe I can help you with your problem today.

jstinehelfer :

In Windows 7 you would use the Command Prompt to use the arp command. If you need to understand how the arp command works then open command prompts then type

jstinehelfer :

arp /?

jstinehelfer :

click enter and this will give you all the command line switches that goes with the arp command

jstinehelfer :

If you need to know where your command prompt is then click start then in the search bar type command prompt

jstinehelfer :

or you can shorten it down to CMD and it will come up as well.

jstinehelfer :

If this fixes your problem then that is great. If it does not fix your problem then please ask for more help

Hi John,

Customer :

Hi John, Thank you for your feedback. I still have some problems and will first give you some background. I am in Cape Town in South Africa and am in the copier industry. I have a dealer about 1,500 km from here who has a problem as they did something on the machine which they should not have done. One possibility is to uuse the arp command to assign a new IP addy to this multi functional device in the hope of sorting out the problem. I have done some testing here in CT and used the following command line in an attempt to add an IP address to the device network card. arp -s 172.16.1.43 00-20-6b-5d-f2-53. Left a space between the IP addy and the MAC addy. Under Windows 7 I get "The arp entry addition failed: Access denied". This happens with DHCP on or off. In a Windows XP environment I can use the above command without any problem and the addy gets added to the device.

Customer :

Please advise. Kind regards. Claus

jstinehelfer :

This looks like it is a Vista and Windows 7 problem. I researched the Microsoft support website with no results. I did do a google search and found that others are having the same problem. I believe this is a problem with 64bit operating systems.

jstinehelfer :

This link explains you need to use a different command to achieve the same goal.

jstinehelfer :

This link is basically backing up the first link I gave you with others having the same problem

jstinehelfer :

So it looks as if there is not a solution to fix the arp command but a work around using the netsh command

jstinehelfer :

so you can still achieve the same goal.

jstinehelfer :

But then I just seen in your question you are using 32 bit so this must be a windows 7 problem as a whole.

jstinehelfer :

I do know it has caused people on Vista to have the same problem. Which I believe Windows 7 was a spin off of Vista.

jstinehelfer :

Let me know if this helps

Customer :

Hi there,

Customer :

Slowly getting there. May have another question or two in a couple of hours.

jstinehelfer :

Let me know how this works out for you.
