Please start your Windows Server virtual machine now. It will be used immediately after the course begins. If you don't have a Windows Server VM, please tell the instructor as soon as possible.
Please open the first manual (505.1), turn to the first lab entitled "On Your Computer" on page 12 or thereabouts, then follow the instructions in the lab to get your VM set up for the course.
If there are any VM problems, it's best to find them now. Have Fun!
