This is brief. Just would like to point out that if you are thinking to install SharePoint on Windows 2008 then heres something for a thought. Windows 2008 doesnt come with WSS 3.0 as default. Hence you need to install it yourselves. But the problem is when you want to do that - it will not allow you. It will ask for Service Pack 1 to be installed. The rational question to ask is, how can i install sp1 when i dont have the wss installed at first place. The answer is, you need to install WSS bundled with SP1. Heres the link to do that :-).
