Writing a BGINFO like Script: Displaying MAC Address information with WMI via the Win32_NetworkAdapter class

I recently had to provide the information displayed with BGINFO on a number of systems. Unfortunately, BGInfo only generates a bitmap, so far as I know, so I decided to write a script to generate the information and use this displayed information to send back to the person who requested it.

The function below is a part of the script I mentioned. It retrieves and returns text that represents the total space and the total free space on all the physical hard drives in a system.

You can view all the scripts in this BGINFO series here.

Here is the code:

Function GetMACAddress(strComputer)
Dim colItems, objItem, address
Dim StrQuery
Dim objWMIService

StrQuery = “SELECT * FROM Win32_NetworkAdapter”
Set objWMIService = GetObject(“winmgmts:\\” & strComputer & “\root\CIMV2″)
Set colItems = objWMIService.ExecQuery(strQuery,,48)

For Each objItem in colItems
if objitem.MACAddress <> vbnull Then
GetMACAddress = GetMACAddress & vbTab & objItem.name & “: ” & objItem.MACAddress & VbCrLf
End If
Next
End Function
