Understanding Microsoft stack technologies is an important aspect of supporting Dynamics CRM. Staying current with all of these technologies takes time on your part to read and understand how these stack technologies work and what features and functionality you may want to use with Dynamics CRM. There are a number of different books, classes, blogs, etc. out there, but one resource that is often overlooked is our free MS Press books. I wanted to share a blog post from another co-worker at Microsoft (Kim Spilker) who highlighted some of the more recent free ebooks available for download right now. SQL Server 2012, SQL Server 2008 R2, Windows Server 2008 R2, Office 2010, Windows 7 and many more! These books can be a great resource even if you are not supporting Dynamics CRM specifically.
