I am using ArcCatalog to connect to published services by local data partners. I have successfully established connections for many services.
One on particular is stumping me.
I am able to see the REST services in a browser (IE and Chrome). However, if I try to connect via ArcCatalog using: http://gisweb2.durhamnc.gov/arcgis/services I get an error message.

I can launch the services through the REST point in JavaSript, ArcGIS Online… but not in ArcMap. For example by clicking on ArcGIS JavaScript or ArcGIS.com Map:
http://gisweb2.durhamnc.gov/arcgis/rest/services/DurhamMaps/BikeMap_NAD83/MapServer
Any ideas?
