I have a Dell server with Windows Server 2008 Foundation installed. I am now on a larger network which has their own servers for authentication and the Windows Server 2008 Foundation will not let join a domain with more than 15 users. I was told that I needed to upgrade Windows server 2008 foundation to Windows server 2008 Standard and that process can be done "in place" but I can't find how do do it. I called Dell and they said they basically said they didn't know what I was talking about.
How do I do this?
