We recently installed a Dell PowerEdge T-110 II server. The operating system is Windows Server 2012 R2 Essentials, which was pre-loaded by Dell prior to shipment. When I check the Windows event logs on the server, I see a repeated error indicating that the "installation of the proof of purchase from the ACPI table failed. Error Code 0xC004F057." I have found the relevant Dell technical article that indicates how to replace the temporary OEM product key with the genuine Windows Server product key. Here is my question: Is the Windows Server 2012 R2 Essentials product key that I want the one that is on the small silver label on the top of the Dell server? Before going through this process, I want to make sure that I am using the correct permanent Microsoft product key.
Thanks very much for your assistance with this.
