From http://www.expta.com/2009/06/windows-server-2008-r2-service-pack.html

You may have known that Windows Server 2008 RTM shipped as Service Pack 1. This is because the Windows Server 2008 code base is shared by Windows Vista, and Windows Vista was at SP1 when 2008 shipped. Windows Server 2008 SP2 was released on May 26, 2009 and was the first service pack you can actually apply to Windows Server 2008.

Unlike Windows Server 2003 R2, which was based on the same code base as Windows Server 2003 SP1, Windows Server 2008 R2 is based on an entirely different code base (Windows 7). The Windows 7 code base is derived from Vista, but is actually a seperate kernel. This change in strategy was required to address challenges that 2008 R2 faced, such as hardware platforms with many processor cores and new power saving features that couldn’t be addressed by keeping the same kernel as Server 2008.

For this reason, Windows Server 2008 R2 RTM will ship as service pack level SP0, not SP1.

Good to know as I plan on upgrading all of my SCOM R2 Servers to Windows 2008 R2.

  1. Hi Tim,

    You say you are planning to upgrade all of your SCOM R2 to Server 2008 R2. Do you know if SCOM 2007 R2 will be compatible and supported on Server 2008 R2. After all it is a separate kernel from 2008 RTM, also the next version of PowerShell included and so on.

    I am going to deploy it soon and I’m wondering whether to start on Server 2008 RTM with SP2 or to wait few more weeks and start directly on Server 2008 R2.

    Thanks in advance,
    Lubo.

    • Being that Server 2008 R2 is not out yet they have not released a statement. But my guess would be that they would support it. I have been running Windows 7 RC builds and they have added a bunch of tweaks to make sure everything that works in Vista works in Windows 7. I would imagine that that being that Windows 7 and Server 2008 R2 are the same kernel they would carry over.

  2. Thank you for your reply. I also thought based on the Vista –> Win 7 app compatibility that Ops Mgr should run on Server 2008 R2, but it is always better to find someone to support your thoughts 🙂 Maybe I’ll wait till there is an official statement from Microsoft.

    Thanks once again.

  3. Server 2008 R2 left out dotnet framework 3.5 until some service pack release. Is my assumtion correct? any one have found the information already, Please let me know.
