I have been working with server core for about a month now. The first thing you will notice about server core is that there really is no GUI interface. Like most administrators we tend to get a little lazy and don’t keep up with all the command line statements to get simple tasks done. Thankfully there are other administrators out there that realize this. So they create nice little programs that help us command line challenged people in our daily job. Below are the links to the GUI configurators that I am aware of. I have also included a couple blog posts that go into detail on some of these tools.
This is the one that I would highly recommend but it currently no longer available from the creator due to intellectual property issues. This tool can be found at some sites such as www.4sysops.com.
