Could someone please clarify what my host Operating System should be for my KMS Host? I keep getting spun around in circles reading the documentation. I need to be able to activate Windows 2008 Server R2, Windows 7, and Office 2010 ProPlus. I'd like the host to be Windows 2003 SP2, but I can't tell if that's a supported solution for all three clients. Thanks! :-)

Hello, as you have the need for activation of Office 2010 you MUST use Windows Server 2008 R2 or Windows 7(Volume license) as the KMS host machine.

Hi, Since you would like to activate Windows Server 2008 R2, Windows 7, and Office 2010 ProPlus, I am afraid that you have to use Windows Server 2008 R2 as your KMS host. http://technet.microsoft.com/en-us/library/ff793412.aspx http://blogs.technet.com/b/office2010/archive/2009/08/24/volume-activation.aspx Tim Quan ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question.
