What is Windows Server 2008 Core?

A. As Windows Server grows in functionality and subsequent number of components, organizations are able to get more and more out of their Windows investment. However, such OS growth has its downsides: More components means more items that need to patched and updated, and more components potentially means more vulnerabilities and a greater attack vector.

With Windows 2008, Microsoft has addressed these concerns by introducing a new Core installation type, which you select during the installation of the OS. The Core installation contains only 25 percent of the bits in Windows 2008; everything else is add-on functionality. Server Core installations have support for the following server roles:

  • Active Directory Domain Services
  • Active Directory Lightweight Directory Services (AD LDS)
  • Dynamic Host Configuration Protocol (DHCP) Server
  • DNS Server
  • File Services
  • Print Server
  • Streaming Media Services
  • Internet Information Services (IIS)

Supported features include:

  • Microsoft Failover Cluster
  • Network Load Balancing (NLB)
  • Subsystem for UNIX-based Applications
  • Windows Backup
  • Multipath I/O
  • Removable Storage Management
  • Windows Bitlocker Drive Encryption
  • Simple Network Management Protocol (SNMP)
  • Windows Internet Naming Service (WINS)
  • Telnet client
  • Quality of Service (QoS)

One missing component in Core is the Windows Explorer interface, so the shell is a command interface. The oclist.exe file is used to list the roles available and to add and remove (except for AD, which should be enabled via Dcpromo).
