Configuring Two Servers to Share Applications

Consider the following situation, you have in possession two servers, let’s call them Server One and Server Two.
Server One has all the graphical software such as AutoCAD while Server Two has all the regular software and it is the server catering to the users.
Both servers are not linked in any way – They are not in a network. If you would like to give a certain user from Server Two access to a certain application in Server One, how would you go about configuring that, without compromising security in both servers?
