A new customer has an existing installation of Windows Server 2003 and I want to update the product key but it's proving not so easy.
I have followed the steps here: http://www.experts-exchange.com/Operating_Systems/Windows_Server_2003/Q_20915230.html
and here: http://support.microsoft.com/default.aspx?scid=kb;en-us;328874
(although this says Windows XP only).
Using the oobe.exe and changing the WPAEvents registry key is not 'de-actvating' the server. It keeps saying "Windows is already activated" so I have no way in. How do I go about changing the product key?
If I have to reinstall, I'm assuming it doesn't touch Exchange, AD and the likes?
