I've recently seen that the three MOC-Courses (MOC = Microsoft Official Curriculum) around Windows Server 2003 R2 technologies have been released.
I did the technical reviews of those MOC-Courses and I'm really satisfied with them. The first one is a two-day class which will show you how to use Windows Server 2003 R2 to support your needs in Branch-Office scenarios, the second course (one day) will teach you the new features about Storage and SAN-Management, and the last one will teach you how to implement a Active Directory Federation Services Relationship internally or with your business partners.
The course does not only increase your experience by a lot of hands on labs, but also teaches you how to design your infrastructure and provides a lot of examples which command lines you can use to administer or implement the features.
