Hello,

I was able to active Windows 2012 KMS key on 2 KMS servers Windows 2008 R2 and Windows 2012 KMS successfully.

However I am not able to activate the same KMS key on 3rd KMS server its giving invalid product key.

I was able to use same KMS key on first two server without any issues.

Please let me know if any constraints in using KMS key on multiple KMS servers.

Each KMS key can be installed on up to six KMS hosts, which can be physical computers or virtual machines. After activating a KMS host, the same host can be reactivated up to nine more times with the same key.

If the organization needs more than six KMS hosts, You can request additional activations for the organization’s KMS key by calling the Activation Call Center to request an exception. For more information, see the Volume Licensing Web site at http://go.microsoft.com/fwlink/?LinkID=73076.

Hi,

Additional, please confirm your key was selected correct, with KMS, product keys are associated with a product group and can activate the Windows editions within that specific product group as well as any editions lower in the product hierarchy. The first and least-inclusive group of the hierarchy is the Client Volume Licensing product group; Server Group C is the most inclusive group in the KMS hierarchy.
