When you install Windows Server 2003 it needs to be activated just like XP and Vista do. When you buy the operating system it will usually comes with 5 user licenses. If you plan on using it as an application server (Terminal Services) those 5 licenses do NOT mean you can connect up to 5 users to the server. You still need to purchase Terminal Services User Licences for every user you plan on connecting. Those 5 licenses that came with the operating system are Windows licenses. So let's say you have 10 users that need to connect. You then need 10 user licenses AND 10 terminal services user licenses for a total of 20 licenses for your 10 users. Confused yet? Well it gets better.
