Yup, its the built in one. I'll definitely try the secondary feed. I wonder how many users have their CI server, deployment server and deployment agents running within the same "network domain" (so that the machine name is resolvable). I've got the deployment and agent running on the production server to keep deployments quick, but since the build server is located elsewhere so as a default the machine name doesn't help when I publish. I realize of course that the internal nuget server is not recommended so perhaps I'll try to work out something else.
