We have a working KMS server in our environment. Currently it's set to activate Office and Windows 7. This works fine.
I am experimenting with server 2012 as a possible desktop replacement for our VDI environment. I know that the KMS server will not activate Server 2012 as I need to upgrade it, so I have activated my 2012 desktop with a MAK key. However, this desktop has installed on it the same version of Office that I have installed elsewhere that activates just fine, but the copy on the 2012 desktop will not activate. The 2012 desktop lives on the same network segment as the rest of the VDI environment where Office activates without issue. Does any one have an idea why this might be?
