“Your Group Policy Fundamentals, Security, and Troubleshooting Book Rocks, Sir! Keep up the excellent work! One thing a like about your style of writing is with my job I am working on various projects at the same time but because of your ability to explain the subject matter, I can put the book down and pick it back up when time allows and I feel like I never put it down. Good job!!”
