Windows Administration is a very big section of GSEC course, you would find it easy if you are a system administrator maintaining Windows ADs and Server security. Otherwise, that section is going to be tough, I have posted a book in the second page of first post on this forum section, you may refer to it and review the books if you are interested in additional materials. The bottom line is that if your company reimburse for exam, the reason to grab GISP is because it gives you 750 questions just to prep for CISSP, pass that GISP and got the company to pay for that amount, you get a cert and in addition it ensures your good for CISSP.
