Thank you for your reply. Same network.

You should be able to use WMI to query the remote hosts for information about its NICs, and get its MAC addresses that way.

The Address Resolution Protocol (ARP) is what all computers and routers today use to retrieve other hosts MAC addresses. Using the ARP protocol directly on a host might be another approach.

Thank you for your reply. I am new with VB .Net. I have no idea how to do it.

here is a link with wmi, but that assumes that the other computer is windows based.

why not run dos commands from vb, ping the computer, then
arp -a
and parse the output.

process.start

here is a link for the Process class

Thank you. I have adjusted it a little because i was getting some errors.
here it is:

Code:

---

        Dim ComputerName As String
        ComputerName = "test"

        Dim theManagementScope As New Management.ManagementScope("\\" & ComputerName & "\root\cimv2")
        Dim theQueryString As String
        theQueryString = "SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = 1 "

        Dim theObjectQuery As New Management.ObjectQuery(theQueryString)

        Dim theSearcher As New Management.ManagementObjectSearcher(theManagementScope, theObjectQuery)
        Dim theResultsCollection As Management.ManagementObjectCollection = theSearcher.Get()

        For Each currentResult As Management.ManagementObject In theResultsCollection
            MessageBox.Show(currentResult("MacAddress").ToString())
        Next

Good to see you succeeded. Im in the middle of writing a DLL for you to send ARPs to other hosts, I'll finish it and post it here in case any one else is interested.
