Gurus,

Running Windows Server 2003 SP2.  How can I obtain the MAC address of a 
remote machine via a WMI Script?  The script would need to create a WMI 
object and then access the Win32_NetworkAdapter class, which has a property 
that returns the MAC address.  I< unfortunately, haven't a clue on how to 
write one.

Hi,
We've all been through this..
Google 'WMI code creator'
Anyway here's your script (in vbscript)
<code>
strComputer = "domain\name"
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root
\CIMV2")
Set colItems = objWMIService.ExecQuery( _
    "SELECT * FROM Win32_NetworkAdapter",,48)
For Each objItem in colItems
    Wscript.Echo "-----------------------------------"
    Wscript.Echo "Win32_NetworkAdapter instance"
    Wscript.Echo "-----------------------------------"
    Wscript.Echo "MACAddress: " & objItem.MACAddress
Next
</code>
The script needs to have the proper rights on the machine it queries
Running on my machine it lists 12 instances, and 4 different MAC
addresses.

Have fun with that ;)

Does this VB script make a Windows API call to obtain the remote MAC 
address?  I can't tell by the code.  Forgive my ignorance!

It's a simple WQL request (SQL like for WMI) to list all instances of
Win32_NetworkAdapter class
then, for each of the results, it prints the MACAddress property.
So it's all WMI, works on any remote computer provided you have the
proper user rights (that is admin) on the account that runs the
script.
If you want to logon as another user, google or msdn search for
Management.ManagementScope (I use that in VB.NET)

Hope this helps.

It definitely worked.  It picked up the remote MAC address of the machine 
for which I intended it.  It also picked up some other MAC addresses as well 
which was kind of weird.

What I did was alter line 1 of the script changing it to:
strComputer = "DC1"

which resulted in it displaying the MAC of machine DC1 (DC1 has only 1 NIC, 
no other NICs present at all).  However the script also displayed a MAC of 
50:50:54:50:30:30. Kinda weird, huh?

I know. tested it on two computers (both running win xp pro, both with
only one NIC) and on both it reports 10+ instances, with 3 differant
mac addresses.. I don't know what the others are though..
So to be sure, you can change the request to "SELECT * FROM
Win32_NetworkAdapter WHERE DeviceID=1"
If I remember correctly the mac address of the first device listed is
the good one.
Glad it helped.

I see that exact number show up on a hardware
listing script that I use. Maybe there are particular
MAC address constants that represent  various
hardware/protocols? I don't know. But in case it's
of use, here's the return of network adapters that was
spit out by an HP PC:

Your number is in there under WAN Miniport.

   I also noticed that a number of items were
returned twice, but only once with a MAC
address. The first item returned was the actual
ethernet card, but its MAC address was only
included with the second instance.

   I have no idea of what the explanation is
for that.

That worked nicely.

Good info on the WAN Miniports, I verified and it makes sense.  I never have 
really understood what WAN Miniports really were for but I know they have 
something to do with remote networking.

I think it is safer not to rely on network adapter device id. You can use 
Win32_NetworkAdapterConfiguration with IPEnabled = true


strComputer = "ComputerName"

Set objWMIService = GetObject _
("winmgmts:{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")

Set colAdapters = objWMIService.ExecQuery _
("Select * From Win32_NetworkAdapterConfiguration " _
& "Where IPEnabled = True")
 
For Each objAdapter in colAdapters
WScript.Echo objAdapter.MACAddress
Next

That worked nicely also.  Why do you say "safer", btw?

Second question is, one has to directly modify the script on line 1 to enter 
the computer who's remotye MAC addres I want to find.  How can this script 
be modifued such that it prompts you for the name of the remote computer, 
you enter it in and hit OK and then it finishes out normally?

cpu = Wscrpit.stdin.readline  'that is to read user input
Now if you want to ensure the input is, at least syntaxically, a
correct computer name, that'a a whole other story.

  That assumes that Spin is using console,
but he mentioned clicking "OK". If you're going
to only give the console method it might be a good
idea to point that out, since it's not typical usage.
For normal VBS it would be:

cpu = InputBox("Enter name of remote computer.")

Because there is no guarantee that Win32_NetworkAdapter.DeviceId will always 
be equal to 1. As far as I can remember it normally is, but if you select IP 
enabled network adapters, you don't have to worry about device id.

How would that work in a script?  The below doesn't quite work, I get an 
error on line 4. :(

'Begin Script
cpu = InputBox("Enter name of remote computer.")
strComputer = "computername"

Set objWMIService = GetObject _
("winmgmts:{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")

Set colAdapters = objWMIService.ExecQuery _
("Select * From Win32_NetworkAdapterConfiguration " _
& "Where IPEnabled = True")

For Each objAdapter in colAdapters
WScript.Echo objAdapter.MACAddress
Next
'End Script

Woops.. I read his message a bit fast (and answered with equal
celerity) and I was sure he wrote "and hit enter"

Rob', ashamed to learn that 'normal' VBS isn't console -_-'

   I guess that depends on one's point of view.
If this were a Linux group I would have been
set upon by a pack of feral geeks for what I wrote. :)

Erm.. That would be
'Begin Script
strComputer = InputBox("Enter name of remote computer.")

Set objWMIService = GetObject _
("winmgmts:{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")

For Each objAdapter in colAdapters
WScript.Echo objAdapter.MACAddress
Next
'End Script

And you're done!

  I'm afraid I don't have any experience with remote
WMI. If strcomputer should be the name of your
remote PC then you want:

strcomputer = InputBox("Enter name of remote computer.")

  Then error-trap that to make sure that a name
was actually entered. strcomputer will return whatever
was in the InputBox prompt:

 If Len(strcomputer) = 0 then
   MsgBox "Error. Remote computer name is required."
... etc.

  So if your remote PC is named, say,
Harry, then hopefully strcomputer contains "Harry"
after InputBox returns.

  Then if
\\Harry\root\cimv2
is valid then you're all set.

That worked!  You ROCK THE HOUSE!!!
