Good self learning IT resources?
 

I've set some goals for myself regarding my IT future and I am really wanting to get exposed to more things. Right now I am a intern/sole IT person for a senior home and I'm ok at AD, slowly poking my way around Exchange, keeping an eye out on connections etc but I don't know things as well as I would like. I don't except to have professional level understanding right now but I don't think that I'm at a level where I should be. I really do not want to be doing help desk level stuff for my whole life.

Right now I would really like to learn more about Exchange as there have been some situations where I've had to stumble my way through and hope I don't screw anything up. Are there any good (free?) resources out there that I can maybe start learning more about Exchange? I don't really need to know so much as to how to set it up, but rather play a maintenance roll.

The way I'm setting myself up to learn is that I learn the broad basics to keep things going and then learn more advanced stuff as time passes.I hope that when I'm out of school, whenever that maybe I will have enough hands on experience that I can handle most task without the look of WTF on my face but also be able to use my knowledge combined with my experience that I could do advanced stuff. It's better than where I kind of currently sit with plenty of book/lab but not a ton of real world.

I found http://www.petri.co.il/ to be quite good when starting out. But the best way to learn is to build a setup at home and practice on it IMO.
