Microsoft offers both current and past issues of TechNet Magazine in CHM format as free downloads. You can even get also receive free subscription via mail if you qualify (I believe you have to have some sort of buying influence in the company) here so be sure to mention your influence, even if you’re stretching the truth. TechNet Magazine is great bathroom reading for any Windows Administrator — it covers just about any Microsoft product you can imagine. Today, I found the article on Microsoft Identity Integration Server particularly helpful (and will write about that shortly).
Also, I attended a pretty good roadshow yesterday on Unix and WIndows Integration. It was informative.. I actually came to work today and used some of the info I saw there. If you were unable to catch the show, you can download the slides on their website. Topics include Identity Management in heterogeneus networks, relational database integration and virutalization tips and tricks.
