An acquaintance of mine (cheers Ray) found this after I asked him a few Server Core questions yesterday. The Core Configurator 2.0 is a graphical frontend to a collection of PowerShell scripts that will allow you to configure your Windows Server 2008 R2 Core VM very easily.
After downloading it locally, use the vSphere client to mount the ISO file on your VM. From within the command prompt on the guest OS, change drive to your CD / DVD drive (D: in my screenshot below) and just run the”Start_Coreconfig.wsf” file.
This opens a GUI with a few options for configuring Server Core.
I'm not going to go into too much detail about what can be done, try it yourself. But just as an example, compare the following window with the steps to configure networking using the command line.
Fantastic tool. I'll be adding it to my toolkit for sure.
