We are getting ready to deploy HBSS on our network per security guidlines. Going through the settings we found out that the McAfee ePO server isn’t supposed to be domain joined. Kinda goofy but that’s easy to deal with. As we read further it says that if the ePO server is virtualized then the host can not be domain joined. Fine, so we repurpose an old server, install the OS but it’s not activating because it’s not domain joined. Here is the simple solution.
First, change the product key if needed using these: http://technet.microsoft.com/en-us/library/ff793406.aspx
Next open a command prompt and enter slmgr.vbs /skms [ip address] where [ip address] is the address of your KMS server.
Then type in slmgr.vbs /ato and it should activate.
