>What I understood is that there will not be any use for web services in the intranet because it can be always replaced with server side classes which respond faster to the users queries?

Well, that's not quite what I said I don't think. If you have a ASP.NET WebForm, then the code-behind can directly access the server-side classes. If you have a WinForm, then you'll need to access the server-side stuff through a Web Service.
