Windows KMS Setup Keys

Well, Microsoft's KMS is so simple that most think you don't need much documentation to get it going. The only problem with that theory is that with the absence of documentation (or the presence of documentation that assumes you've already been running Vista (yeah, right!) and have KMS already), you can make some incorrect assumptions.

We did that with our KMS rollout, and got ourselves into the position where our images had been setup using the wrong key, the KMS key, which made them all think they're KMS hosts, rather than clients. You can see what mode they're in using the slmgr.vbs /dlv command.

You can easily revert them to being a client by issuing the slmgr.vbs /ipk {setup key} (you may have to issue a slmgr.vbs /rearm first though). The only problem here is finding the setup key. If you have original media it might be included with that, but if you downloaded from the Volume Licensing Centre, it's not provided (or it wasn't in our case).

So, you can get these setup keys here:

Once we got our machines back to being clients again, they found the KMS server no problems, and off we went, activating like clockwork! Running the slmgr /dlv command again showed the partial product key matched the setup key, and eventually the "License Status" section changed to "Licensed".
