Books & training for Building Servers?

I’m fairly new to the field (just graduated from a local college and got my A+ at the same time. However, the amount of information covered about the details of building servers (file, print, DNS, etc) were somewhat vague, as the Associate’s I did centered more on Tech Support & Helpdesk. I want to start learning more about building & maintaining servers, but I’m not sure where to start. Any recommendations for books/CD’s/possible courses?

Thanks in advance.
