Hi all, Newbie here, not sure if this is the right area to post this thread, but, I have a problem. Installed 2008 Datacenter edition, the installation went fine. After the install it keeps on nagging about activation. Activation fails every time. This is a genuine Windows Server with MSDN licensing. How do I bring up the activation window? I can't find it any where? furthermore how can I activate the server, (specific steps, please) Thanks, _admin_
