We are a college trying to activate some Windows 7 machines from a Server (2008 R2) running KMS activation.
We have tried contacting Microsoft but unfortunately we are always put through to a call centre in India and as the assistants don't understand our question phrasing, we are being passed back and forth to the same departments without resolution
The problem is to do with activating the client.
The KMS key (beginning with B) says "it can’t be activated as the KMS server determined the key could not be used."
We have activated a couple of Win7 clients but all of a sudden this message is all we get.
Any help would be appreciated.
