IIS 6 Manager
If you're running Windows Server 2003 on your domain and your workstation is on XP, you need to get Internet Information Services (IIS) 6.0 Manager for Windows XP. This tool is great! It updates XP so that you can manage your 2003 Server IIS instances remotely, and you can manage your local instance with the new, fancier GUI. It's a must-have, especially in a corporate environment.
