KMS server en clienst were setup in June 2012. It went ok for months en de clients (Windows Server 2008 r2 SP1) had a license status "Licesend".
Now the license status is "Out of tolerance grace" trying to activate I get the message: "The software licensing service reported that the computer could not be activated
the count reported by your Key Management Service is insufficient
Please contact your system administrator"
How can I get the Servers to activate so I get a license status "Licensed"?
