My good friend Kerrie Meyler, is already a guru and her books can help you get there. Kerrie has written one great book on System Center Configuration Manager 2007.
She is also is writing another great book on System Center Operations Manager 2007 R2. The trick with R2 is currently only being scheduled to be in electronic form, unless there are enough pre-orders for the book. So if you want to get a hard copy of the R2 book, check it and you can read more about her upcoming book here:
In Development – System Center Operations Manager 2007 R2 Unleashed
Enjoy the books and if you have read her books, let me know what you think!
