Mistakenly, I have ran the slmgr.vbs /upk command on the Microsoft Windows Key Management server.
Now, it is asking for 'Activate and validate your server product key' and when I am doing manual validation it is asking for Product key of the server (I do not have any information about the product key).
We have another KMS server in the same infrastructure which is up and running fine (Microsoft windows server 2003).
Key Management server - Microsoft windows server 2008 R2 Service Pack 1.
Would like to re-activate the Microsoft Windows and KMS server again.
