I have been using a test system for awhile with server 2008 installed. I just recently realized it needed to be activated unless I wanted to lose access to my virtual lab...
So I went to activate the server using "show me other ways to activate"... The hyperlink was unavailable.
By unavailable, I mean I would hover with the mouse over it and it would not behave as a link...
I performed my usual troubleshooting steps: logoff/logon, reboot to no avail.
I next proceeded to change the product key but fed it the same product key I used to install. Once done, I went to activate windows again. The links were available as expected. Windows hoodoo...
The activation worked using the activate by phone feature if you are wondering. Business as usual.
