2003注销脚本如何编写

我做了个登录脚本如下：gr.vbs
Dim net  
  Set net = CreateObject("WScript.Network")  
   
  ' mapping net work drivers  
  net.MapNetworkDrive "L:", "\\223.223.2.251\grdx$","True"  
  net.MapNetworkDrive "M:", "\\223.223.2.251\gr$","True"  
  net.MapNetworkDrive "z:", "\\223.223.2.251\grtemp$","True"  
 
   
  ' Create desktop shortcuts  
  Set Shell = CreateObject("WScript.Shell")  
  DesktopPath = Shell.SpecialFolders("Desktop")  
  Set link = Shell.CreateShortcut(DesktopPath & "\digicentury.lnk")  
  link.TargetPath = "http://www.xxxxx.com.cn"  
  link.WorkingDirectory = DesktopPath  
  link.Save  


现想关机时注销它,如何写，要不然每次开机说盘符存在的提示。

2003我才刚用，不懂。

关机时运行这个命令
net use * /del
