    Are you wanting to find the MAC address for a remote machine that is on your segment of an ethernet network (so use ARP) or somewhere else?

    If the later it will depend on what OS is on that remote machine, and what access is allowed. As a last ditch try ARP on the router for that remote network if you have access.

    Otherwise there is no chance of getting this, and I'm not sure why you would want it anyway!

    actually, when i don't know the answer i find it best to not say anything.

    nah, earlier tonight i had a splitting headache, probably from the heat, and i found i couldn't form a coherent post anymore. so i deleted it. is all.

    anyway, as for the answer to the original question, i second harry's post.

    Harry the reasonI am asking is because I need to setup a reservation on our dhcp server and I cannot be bothered to move if that's okey with you!
    Arp wont work because there are about 5 routers between me and the station that I want to set the reservation for....
    just so you know the workstation got xp pro on....
    guess I have to use a script...
    cheers for the help peeps :biggrin

    Is the machine on the network already getting it's address from your DHCP server?

    If thats that case just find it and reserve it's current address. It's MAC address will be there as well.

    And I'm sure Harry doesn't mind if you move or not.

    Is there any reason that you don't call the person who uses the machine and ask them to read it to you?

    Er - I have no problem if you move or not! :biggrin

    And DHCP won't go through routers, unless you have done something special with them.

    Depending on the relay agent you may find that ARP in fact works, as long as it is done on the DHCP server box.

    And this is somewhat specialized - it would have been only fair to mention some of this in the original question! :p

    there a simple answer to this
    If you want to determine the MAC address of another computer, simply ping the computer by opening the command prompt and typing ping followed by the IP address assigned to the remote computer. Since the IP address has to be resolved to the MAC address, an entry will be added to you physical address translation table. At the command prompt type arp -a. The results will display the IP address and the MAC address of the remote computer.

    Yes - this is how you would normaly do it. However - you said earlier that ARP wouldn't work because of routers. So I am not quite sure what you are trying to say here.
