I have installed a 2 Node CCR Cluster with the following specifications: 1. Windows 2008 x64 Enterprise Service Pack 2 2. Exchange 2007 Service Pack 1 The Windows 2008 installation is Volume Licensed and Successfully Activated for both nodes. However when I tried to enter the License for the CCR Cluster using a Volume License that has been used for Enterprise Activation in other office branches I get the following message: (screen shot will not paste)(Of Course I cut out my product key for this publication!) I then upgraded the CCR to Exchange Service Pack 2 and tried again I received the same error. I also tried installing the Product Key from the Exchange command shell with the following result: (screen shot will not paste) (Again I removed my product key in the illustration) The Error clearly indicates a key problem but the strange this is that other offices are installing Enterprise Versions of the Software with the same key! Am I trying to License the nodes incorrectly? Your assistance would be greatly appreciated. Also Note, this key works fine when Licensing Standard Installations.

Can you manuallly type in the error here. Screen shots will not work here.Can you try this command againset-ExchangeServer SERVERNAME -ProductKey aaaaa-aaaaa-aaaaa-aaaaa-aaaaaRaj
