KMS Client count went down - how or why?


  • I have a windows 2008 R2 KMS server that I had 25 Windows Client devices registered again, therefore the server was handing out activations.  This seemed to work for about 1 month.  Now when I'm trying to add a few more machines I get an error indicating that my KMS server does not have enough activations.

    When I look at the slmgr /dlv is see the current count is down at 16.

    Any ideas why my server reduced it's count and will no longer activate my new clients?

  • Hi

    Any error in your evenglog ? You will see activation attemp there.

    Did you cloned some PC or imaged ? The KMS ID will be the same in that case, thus can give some problem. The server will see the ID, but will log it can activate them as it's already activated for another computer name.

    Please check that link too;
