Cannot activate server 2008 r2 server kms unavail

hi guys,

Strange issue, one of our servers shutdown today and said it needed to be re-activated. It was a server we inherited when we took over the network. Here is the error message:

When trying to activate you get 0xC004F074 with description "The Key Management Server (KMS) is unavailable

KMS licensing requires a properly configured in house KMS license server. If you are not running a KMS server inhouse then you want to install a MAK license key on your inherited server. Once the MAK key has been entered you can activate it online or by telephone.

What's a mak key? Why would this just happen all of a sudden?

Here is some instructions to convert from KMS to MAK,

Scott GorcesterCTOCommented:
A MAK key is a license key that uses a process of activation against the Microsoft Online license clearinghouse. MAK keys are probably what you have been using all along. A KMS key is designed to be activated in house. KMS licensing is especially well suited to VDI implementations and systems where continuous internet connections may be unavailable. I am unsure why it would suddenly start complaining, how long has it been on your network? I would not expect a properly activated MAK license to suddenly switch to KMS so I would guess that it just now came up for re-activation and could not find the KMS host.

Scott GorcesterCTOCommented:
I am assuming that you have not previously operated a KMS host on your network, it you are intending to use KMS then this error is likely to be due to a mismatch in the KMS host vs. the server that is attempting to activate. If you do not have KMS inhouse then simply locate your MAK key and convert the server in question to MAK.
