If you are DirectAccess addict, order this book
I discovered DirectAccess at TechED Barcelona 2008 edition, we can compare it to a technology Lego. I started with lab building, projects, and delivering sessions at Microsoft Techdays since 2009. I even wrote a book on DirectAccess with Lionel LEPERLIER. We wrote it because there was no reference book on this subject, (except Understanding IPv6 third edition that include a dedicated chapter on DirectAccess).
By now there is a reference book on DirectAccess written by Erez Ben-Ari and Bala Natarajan. This book cover all aspects of DirectAccess (except project management).

So like me, if you are a DirectAccess fan boy, order this book now.
