I am currently at a remote location and even though I have internet access (i.e. I can browse the web but not very quickly), when I start ArcMap 10.1ArcMap 10.1 the Add DataAdd Data options for Add BasemapAdd Basemap and Add Data from ArcGIS OnlineAdd Data from ArcGIS Online are greyed out.
Does anyone know why this might be, and whether there is a way I can force ArcMap to "try harder" to reach ArcGIS OnlineArcGIS Online?
