I develop a solution where the SharePoint web part should fetch map from an ArcGIS Server in a closed network without any internet access. The web part do however try to download the clientaccessplicy.xml and crossdomain.xml from services.arcgisonline.com. Since it can't reach them it throws a "Layer Initialization Failure" exception. It is thrown even if i do not have any layers at all. I have removed all connections and other references except for the one to my own ArcGIS server, but it still tries to access services.arcgisonline.com. How do I turn that of?
My local ArcGIS Server and its services are however working as expected and the layers are displayed as they should when I add them.
