Windows Server 2008 was the first Windows Server with the Server Core option (in all editions, except IA-64[1]). Though no Windows Explorer shell is installed, Notepad and some control panel applets, such as Regional Settings, are available. Server Core on Windows Server 2008 does not include the Internet Explorer or many other features not related to core server features.[1] A Server Core machine can be configured for several basic roles: Active Directory Domain Services, Active Directory Application Mode (ADAM), DNS Server, DHCP server, file server, print server, Windows Media Server, IIS 7 web server and Hyper-V virtual server.[1] Server Core can also be used to create a cluster with high availability using failover clustering or network load balancing.
