Answer 1

Ok, so MAK can be a little more sensitive to hardware changes, and, will require re-activation with the online MS webserver (or via telephone).
This can also happen in a KMS environment, but that is usually transparent and re-activates silently.
For your MAK scenario, you will need to re-activate this server.
Follow the activation procedure you used, when you first installed the server.
(probably, if the server does have internet access, you can just execute: cscript slmgr.vbs /ato )
