KMS Activation issue

[pixellip]

Hi there

We have a Windows 7 PC that reports Windows 7 won't activate.

When I try to run slmgr /ato it reports Error Product key not found. It can find a Key Management Server (it reports software licensing service version with a number which is reporting the same number when I try it on other pcs)

 

If I do slmgr /dlv it reports the same.

I've tried clearing the KMS cache and re-joining it to our KMS server ( which it says it has found). DNS is not an issue either.

Short of re-imaging it which would be cheating can anyone thing of anything else I could try please?

 

I've tried removing from the domain and re-adding - no luck.

Really stumped.

 

Thanks for your help

Have you tried pushing the KMS client key to it using VAMT? It's possible that it hasn't got the client key installed - without this it won't check in to a KMS server.

I get this sometimes. Just like the client decides to forget the key.

 

You can push key via VAMT or just as easy to run slmgr /ipk manually. Then slmgr /ato.
