title: Getting Service Tag from Dell Machine using .net?
body: <p>I've got a class that pulls model information (hardware info) 
  for a local machine code is like so:</p>
  
  <pre><code>   Imports System.Management

  <p>Any possibility to get a service tag from WMI ?  From the client side form I display values like so:</p>
  
  <pre><code>   Dim objWMI As New clsWMI()
          With objWMI
              Debug.WriteLine("Computer Name = " &amp; .ComputerName)
              Me.Label1.Text = "Name: " &amp; .ComputerName
              Debug.WriteLine("Computer Manufacturer = " &amp; .Manufacturer)
              Me.Label2.Text = "Manufacturer: " &amp; .Manufacturer
              Debug.WriteLine("Computer Model = " &amp; .Model)
              Me.Label3.Text = "Model: " &amp; .Model
              Debug.WriteLine("OS Name = " &amp; .OsName)
              Me.Label4.Text = "OS Name: " &amp; .OsName
              Debug.WriteLine("OS Version = " &amp; .OSVersion)
              Me.Label5.Text = "OS VERSION: " &amp; .OSVersion
  
              Debug.WriteLine("System Type = " &amp; .SystemType)
              Me.Label6.Text = "System type = " &amp; .SystemType
  
              Debug.WriteLine("Total Physical Memory = " &amp; .TotalPhysicalMemory)
              Me.Label7.Text = "Memory: " &amp; .TotalPhysicalMemory
              Debug.WriteLine("Windows Directory = " &amp; .WindowsDirectory)
              Me.Label8.Text = "Win Directory: " &amp; .WindowsDirectory
          End With
