Change from per device to per user license on Terminal Server 2003

Posted on 2005-04-15
Last Modified: 2008-01-16
I have terminal server which is working in "per device" mode. I have installed License server which has issues "per device" license to all my Devices. I have 15 licenses "per device" issued.

My Question is:
1. Steps to change from Per Device to Per User mode
2. What will happen to the Devices which are running having permanent "per device" license, after the change?
3. Will Microsoft change my per device license to per user so that I can deploy it on the License server.

    1. This is done on the Terminal Server(s), with the Terminal Services Configuration tool; it's under under Server settings\Licensing.

    Careful when adding/removing Windows components afterwards:
    Terminal Services Licensing mode changes from Per User to Per Device after you add or remove a Windows component

    2. Nothing.

    3. No. You'll need separate "Per User" licenses.

    Since you already have "Per Device" CALs, why do you want to switch?

    Thanks oBDA,

    2: Nothing--> you mean user will not feel any change. They will start getting User mode licenses. What happens to the registry entry in their devices which "Device mode" license has created. Will they be keep using Device mode license till it expires and then automatically switch to user mode.

    3. I have per device licenses. Users are using different computers to connect. Thus per user license may be more useful in our scenerio. So we want to change license type " per device" to "per user". Do you know Microsoft accepts these kind of requests and change it or we have to buy per user licenses and our investment in per device licenses go waste if we switch to per user license mode on terminal server.

    2. The user won't feel a change. The client's license in the registry will still be there, but it won't be used anymore (as the Terminal Server now wants to have a "Per User" CAL). You can physically delete the license on the clients if you feel like it:

    3. In that case, "Per User" CALs make sense, of course. In principle, I'm afraid you'll have to buy new licenses. It might be worth the try to call the Clearinghouse (the number is someplace in the Add Licenses wizard) and ask them; they reissue TS licenses all the time when a TS LS has to be moved to a different machine ...
