We don't have much to go on, and that error can mean many things if you are not forcing authentication on the service. How are you trying to access the service? Through jquery/javascript? Code behind? alot has to do with your web.config setup.

Are you accessing the wcf service from remote server. Write Inbound rules in Firewall that will allow the accessing of your service.
