How do I access Desktop central without having to remote connect to server?

I would like the ability to connect to Desktop Central from any computer on the LAN but I find I can only do it by remote connecting to the server and running it through that.

I have tried the following:

http://dc-01:8020
http://dc-01:8383
http://192.168.0.3:8020
http://192.168.0.3:8383

But none of these work also tried with https

Anyone have a clue or am I being stupid and the answer is easy.
