When you have a 2008 server running, are the 2008 licenses in use? Also, if 2008 cals are purchased through OEM, (we have the serial numbers), where could I go to get copies of the certificates. If the server is running with 2008 cals is the physical certificates really necessary?

I would recommend you to contact Microsoft Licensing to get the correct answer: http://www.microsoft.com/licensing/contact-us.aspx Santhosh Sivarajan | MCTS, MCSE (W2K3/W2K/NT4), MCSA (W2K3/W2K/MSG), CCNA, Network+ Houston, TX Blogs - http://blogs.sivarajan.com/ Articles - http://www.sivarajan.com/publications.html Twitter: @santhosh_sivara - http://twitter.com/santhosh_sivara This posting is provided AS IS with no warranties,and confers no rights.
