*Filed*Now buy/download the MCSE 2012: Server Infrastructure books and start studying. As you go through the books you'll learn how to install Windows, learn all about the OS and its features, and learn how to install, administer, and troubleshoot Active Directory.
By the time you're finished (assuming you made labs for everything) you'll have enough knowledge to get a sys admin job.
You can also get the books covering SCCM and Exchange and setup labs for those as well. With an AD, Exchange, and SCCM lab you'll be coasting.
FYI SCCM dudes make bank.
Tell me something tho, when you talk about setting up labs, you're talking virtually or physically?
