Question : Incorporate Server Core Changes in Windows Server 2008 R2

Windows Server 2008 R2 comes with revisions to Server Core. Do those revisions affect your environment and your use of Server Core on a system running Windows Server 2008 R2?

Answer : Incorporate Server Core Changes in Windows Server 2008 R2

Depending on what you use Server Core for in your environment, the following changes may or may not affect you:
  • Active Directory Certificate Services has been added in R2.

  • WoW64 support for 32-bit applications is now an optional feature and not installed by default.

  • New optional features include a subset of the .NET Framework 2.0, a subset of the .NET Framework 3.0 and 3.5 (including Windows Communication Framework [WCF], Windows Workflow Framework [WF], and LINQ, but not including Windows Presentation Framework [WPF]).

  • Windows PowerShell (woohoo!!!) will be functional in the R2 version of Server Core.

  • ASP.NET and additional IIS support have been added. And although you cannot use the IIS GUI console in Server Core, you can use it remotely to manage IIS in R2 if the web management service is enabled and configured.

  • FSRM (File Server Resource Manager) will provide new functionality designed to simplify storage management for all storage architectures.


When the word subset is used above for the .NET portions that have been added, the idea is that the Server Core team didn’t seek to add to the footprint of the system with items that aren’t necessary to Server Core. So, only those aspects that would make sense are implemented.

To install .NET 2.0, you run the following:

Start /w ocsetup NetFx2-ServerCore

To install .NET 3.0 and 3.5 functionality, you run the following:

Start /w ocsetup NetFx3-ServerCore
