A quick note, adding one small but rather important detail to the configurations of Windows Server 2008 (R2) with SharePoint (2010) on it. For testing, develpoment and demo purposes I run a single virtual machine, using using thus the server as client as well as the base server for SharePoint. For full functionality of eg. document libraries the server needs to run the Desktop Experience feature. This enables for example saving documents to doc libraries straight from Office applications and other Explorer related services.
