KMS Server License - redeem

    Question

  • Windows 2012 KMS Server.  Question is simple …

    I installed a Windows 2008R2 in Production and KMS activated it.  After 5 months of use I decommission this Windows 2008R2 server.  Now how do I redeem or KMS releases the license key for this server so I can use it later?  Where is this information kept on the KMS Server?  Hope my question is clear?

    Thank you

  • When a KMSclient becomes activated by contacting a KMShost, the KMSclient "activation status" becomes "Licensed", and this begins a countdown from 180days to 0days.
    Periodically the KMSclient will re-contact the KMShost and renew the activation status, which resets the countdown to 180days again.
    If a KMSclient cannot contact a KMShost for 180days, the "activation status" of the KMSclient becomes "Unlicensed".

    The VA 3 guide is here: http://technet.microsoft.com/en-us/library/hh831612.aspx

    The KMShost does not keep a database of KMSclients at all, it does not keep a record of license keys assigned to KMSclients, nor does it keep a record of activations issued/released. The KMShost keeps a "count" (total) only.

    The KMShost does write to its own eventlogs, each time a KMSclient contacts the KMShost, but this is difficult to use for record-keeping purposes.

    When you create a KMSclient, of any type, you must keep your own records, to ensure that you remain compliant with your licensing agreement. If you decommission a KMSclient, you must keep your own records of that.

  • Your question is clear. You cannot redeem/retrieve/recover an activation in KMS, nor MAK.

    Volume Activation 2.0 and later, does not implement such a concept.
    If you have a server, or client, it is either licensed to have the product installed, or it is not licensed.
    Activation (via MAK or KMS) is not proof of license.
    KMS in particular, performs no kind of validation that you have not exceeded your license entitlement.

    KMS does not limit the number of activations in any way - any/every KMSclient that contacts a KMShost will become activated.

    If you are decommissioning a KMSclient machine, simply do that, and you can then adjust your records (outside of KMS) that you have recovered that license. You can then re-assign that license to another machine, at your convenience, in accordance with your Volume Licensing agreement with MS. There are no other technical/configuration steps to perform.
    KMShost does not know how many licenses you are entitled for, it does not keep a total count.

  • Thank u Don.

    Question ... i am new to this ... when I registered my sever it shows this information ...

    License Status: licensed

    Volume activation expiration: 259200 minute(s) (180 days(s))

    What does it mean?

    ________________________

    Question:

    Where does the KMS keep all the information ...like license keys assigned to the servers? So when I decomission a sever I can see which license key was assigned to to it and make a note to assign it later to a new server???

    thank u for the insight.
