KMS licensing

    Question

  • I'm trying to understand KMS licensing.

    My understanding from what I've read of the technet documents surrounding it, is that one purchases a class of KMS license, (C,B,A,etc), and then the license server will activate as needed.

    How do the per server activation costs work into the equation?

    Do we need to purchase licenses on a per server basis ontop of the KMS license?
    Is there a link or document I can point to to clarrify this matter?

    Thank you very much.

    This would be per installation of Windows as per your license agreement, your volume license agreement should tell you how copies of Windows you are allowed to deploy.

    KMS is simply an activation method, it is not tied to compliance

  • To get the KMS keys you need to have a volume license agreement with Microsoft, after which you can obtain the keys at http://licensing.microsoft.com.

  • Ok, so, there is then I presume a costing model behind the data that the KMS server verifies with Microsoft as more and more systems are configured in the corporate network.

    Any notion as to what those costs are that can be disclosed in the open?

    My company has a Volume License Agreement, but to fact check I basically have to trudge through and find the information myself.

  • Hello Cheshire43,

    Activation is not tied to compliance with your licensing.

    The KMS host does not check with Microsoft, the only contact it makes to Microsoft is when it needs to be activated itself.  This is done to prior enabling the KMS clients to activate.

  • Thank you Darrell,

    The core of my original question is not whether or not KMS contacts Microsoft, but how pricing works around the use of KMS to handle activations.

    I surmise that the purchase of a KMS license (Client VL, Server A/B/C) does not give one free reign to activate an infinite number of windows servers without incurring additional costs.  So how does the cost structure work?

  • Hello Cheshire43,

    This is built into your Volume Licensing agreement as to how many seats you are purchasing. 

    Depending on what you purchase\reimage rights as per your agreement.

  • Ok, so it does still tie into a per authenticated server cost in addition to the KMS class license?
