We have downloaded and installed the Windows 2008 Standard R2 edition months ago. Now the server is in production.
We signed up the Microsoft Partnership Action Pack subscription last week and get a license for Windows 2008 Enterprise edtion.
I am trying to activate the standard edition with Enterprise key as advsied here: Upgrade Domain Controller SKU from Server 2008 R2 Standard to Enterprise , but failed.
Is it because windows 2008 we have is different? (downloaded from MS site with eval license).
This is the error message:
