Windows Server 2008 can be managed using a number of in-box and out-of-band tools. If you only need to manage a single server, use Initial Configuration Tasks and Server Manager. If you need to do this remotely, enable Remote Desktop on your server. If you need to manage multiple servers roles on different machines, install the Remote Server Administration Tools (RSAT) and use each tool to manage multiple instances of a particular role. And if you need to automate the administration of Windows Server 2008 machines, use ServerManagerCmd.exe, WMI, Windows PowerShell, or some combination of the three.
