Set colNamedArguments =WScript•Arguments.Named
DNSDomain = colNamedArguments.Item ("DNSDomainSuffix")
NetConnName = colNamedArguments.Item("netConnName")
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery _

For Each objItem in colItems
If Not IsNull(objItem.NetConnectionID) Then
if objItem.NetConnectionID = NetConnName Then
strMacAddress = objItem.MacAddress

End If
Next
call ExecuteDnsSuffix (WMIEchoStr)
Function ExecuteDnsSuffix(WMIEchoStr)
strComputer = "•"
Set objWMIService = GetObject("winmgmts:"

Set colNetCards = objWMIService.ExecQuery –
("Select * From Win32–NetworkAdapterConfiguration Where IPEnabled =True")
For Each objNetCard in colNetCards
ExecuteDnsSuffix=objNetCard•SetDNSDomain(DNSDomain)
