I just ran into this today as well as I'm trying to get my extranet Access Point to work with On Demand. Can anyone offer any guidance? In fact, I get 3 different responses based on the browser I am using.
1) IE - error 403 user has no rights to access the resource
2) Chrome - Create one in NPrinting or make sure you have access rights
3) Firefox - No connection with NPrinting server. Please check your network settings or contact the administrator.
