Snap Deploy 2 problem

Im trying to get snap deploy to work in a class room with about 20 computers in it. there are several problems that i think are all related. For one thing I cannot log into the managment console even though the login/pw are correct.

If i do manage to get into the console i cannot view any of the pc's running the managment agent.

Does it matter that i have all of the components for managment (license server, managment console, etc.) installed onto one machine? the best practices say that it does not matter but im not too sure. thoughts?
