I am replacing my current Windows 2000 Server with a Microsoft Windows Server 2003. This is also my licensing server for Terminal services and user CALS. I know with Windows Server 2000 it generates warning messages in the Application log when you do not have enough licenses. Is it the same in 2003 or will it stop users from being able to access until the licenses are added? I know I have enough Terminal licenses. I am not sure if we have enough 2003 User CALs. I want to make sure their is no disruption to the users when I make this change. If we are short CALs I will buy, but do not want problems until they are purchased and installed.
