I was needing to apply a secondary W2012 license key to a physical server so that I can add 2 additional virtual server environments to this machine. I'm sure I don't know how to approach this since it hasn't been very obvious thus far. So far I have 2 Windows 2003 Server Virtual servers running great and are in production. The physical server has been licensed for the initial 2 processors. I'm stuck! Let me know what you think. Thanks.
