I've installed Windows Server 2012 Essentials R2 on my server. Then I've bought an OEM licence to add on this server.
I've tried to convert my trial to "full licenced" with my key, but the system always refuse my key :(
I've seen on Microsoft Web site that WS2012 Essentials trial can be converted to full version with the slmgr.vbs
script, but it also refuses it !
I've also read somewhere that the server can't be a Domain Controller to be activated, but it seems that we can't remove the DC role on WS2012 Essentials R2 ?
Do someone have a trick ?
Regards
Edit : This is not a question about licensing, but a question about Activating a licence that I already own : The procedure given by microsoft gives me troubles, I ask for help about commands to make my server accepting my licence.
