How do I draw Microsoft style architecture images?

What software can I use to create architecture drawings like those in the Microsoft Patterns and Practices Application Architecture Guide?开发者_Python百科

Have you tried Visio? I believe Visio has support for this. Also, Visual Studio 2010 has the new "Architecture" feature which supports better class, dependency, layer and other diagrams right out of the box.
