I have a vendor who has supplied a secured ArcIMS image service (with raster data) and I am trying to add in a Silverlight based application. When I try to add this as layer in ArcMap and trying to convert this into MSD, it says that this layer is not supported. I can't really publish this map service as an msd based service. I have been trying lot of different things but haven't found the way to do this. I thought I will ask if other users have tried to do this.
My environment: ArcGIS Server 10
