Hello, I am trying publish a service and this is my first time so my only choice is to create a new one. I have version 10.4.1. When I get to the wizard to guide me through the publishing process it asks for a server URL and I don't know what to enter here. Any help would be appreciated. It is also asking for authentication. Is this my existing ArcGIS Online username and password?
Hi Chris,
You could just sign-in to ArcGIS Online from ArcMap (File > Sign-in).

Then, you can share the map document as a service (File > Share as > Service) to ArcGIS Online.
