Lock Your Computer
By Adam Karim

So, in my quest for the perfect way to lock my Windows 2000 Pro, Server, or Advanced Server since none have the "Window Key" + "L" that was introduced with XP. I've used such things as shortcuts and Windows Scripting host in order to quickly lock it but I wanted something easily transferable. Well, here ya go, easy code to lock your comp:

namespace LockUp
{

 using System;
 using System.Runtime.InteropServices;

 [DllImport("user32.dll")]
 public static extern void LockWorkStation();

 class Lock
 {

  static void Main(String[] args)
  {
   LockWorkStation();
  }
 }
}
