You have likely heard about the “Core” installation role in Windows Server 2008 which does not have a GUI, but is all command line based. This is a great role to use for branch offices, for Hyper-V servers and some other roles that are typically managed remotely.
If you want to install the server core role, but would still like a GUI for the basic configuration your in luck. Guy Teverosky wrote a GUI utility called “CoreConfigurator” that does just that. It can be downloaded from http://blogs.microsoft.co.il/files/folders/guyt/entry68860.aspx. Be aware that this is not supported by Microsoft though.
