Revoke Duplicate Terminal Server CAL device

Hi,

We have some problems in our Windows Server 2008 R2 Terminal server, and some thin clients (wyse) has taken two CAL licenses device (With the same machine name).

To clean the duplicate licenses, I did revoke a couple of them, but I can't clean all the licenses that are duplicate because the TS show me a message like this:

"The Terminal Services client access license (TS CAL) issued to xxxx could not be revoked because the revocation limit for the product TS CAL is reached. . The TS CAL revocation of this product type will be allowed after 2013-02-18.

How Can I force to revoke the duplicate licenses?

Regards

switch to a licensing without device cals ...
if you use user calls the problem does not exist.
if user calls possible you should build a new licensing server and call the clearing house to assign the licenses. ask them for converting device-cals into user-cals ... mostly i have success.

You have to wait.
You can only revoke up to twenty percent of the number of TS Per Device CALs of a particular version installed on your license server.

call the microsoft clearing house.
devices with multiple licenses is not a unknown problem and they should be able to help you.
( more than one time i received additional licenses with no cost)
the local telephone number you can find within your ts-license server.

Microsoft tell us that is a problem with our thin clients, and the manufacturer of the thin clients tell us that is a microsoft problem.
