I am a systems administrator for a small company (50 users) with an NT domain. I have an excellent computer background but do not have any certifications. I am wanting to add some of Comptia's certifications as well as an eventual MCSA. I am needing some advice on what direction to go. There are local companies offering instructor led certification courses which are quite expensive. Is instructor led training worth the money or are self help books and web based tutorials just as good? What are the best self help books to read and websites to view? Thanks very much.
