How do I know if KMS is working?

The first time I had to setup KMS I had no idea where to start. I had the KMS product key but no instructions on how to use it. Its not like your normal activation key so I had to hunt around the net to figure out what to do.

So what that in mind I bring you my quick and easy 5 second guide to knowing if KMS is working.

Firstly you will need to type the following commands from an elevated command prompt, even if you are an administrator (which I assume you would be) you need to run cmd.exe as an administrator.

Installing the KMS key

To install a KMS key type slmgr.vbs /ipk <KMS Key>
ipk stands for Install Product Key, it will also replace the exsisting key if one is already installed the server.

slmgr.vbs /dli will the Display the License Information. This includes the KMS channel, the license status, current count and total cumulative requests received from clients.

KMS in Event Viewer

KMS also logs all its activations to the Event Viewer, you can find it under Server Manager, Diagnostics, Event Viewer, Application and Services Logs, Key Management Service. This can help you with troubleshooting activation issues.
