Hi
I am developing a console app that will run from the command line on a Windows 2008 R2 64 bit server.  Using C++, what is the most reliable method of acquiring the MAC address of a remote Microsoft Windows machine using its IP address?
Thanks

Have a look at the SendARP function: http://msdn.microsoft.com/en-us/library/windows/desktop/aa366358%28v=vs.85%29.aspx

It makes an ARP request and returns a MAC address in its OUT parmeters.

ARP is a good idea, but won't help if the remote PC is on a different VLAN or on a distant network across the internet for example.

ARP uses a broadcast on the same network segment.  If the IP address is on a different subnet the client wouldn't initiate an ARP request for that device's MAC address - instead it would send the request to the default gateway.

Hi - thank you both for your replies - SendARP looks to be the solution. However I was wondering how well SendARP would work if the PC was a virtual PC and/or if there was more than one MAC address at the IP address?
Thanks

A virtual PC will be assigned a virtual MAC address, which will respond to the ARP request.

An IP address can't be used by more than one MAC address at a time, so you'll only ever see the MAC of the device that's actually using the IP at the time.

Thanks. After much testing SendARP() proved to be a reliable solution across all MS Windows platforms.
