Remarks

Map rotation is a property of a map. An exported map image or exported layout image should respect the map rotation value. However, once a MapServer Object has been added to ArcMap it is now a layer and this rotation value is dropped. The reason for this is, in ArcMap, when a layer is added to a map, the layer adjusts to fit the spatial reference and existing rotation of the  map.  If the default rotation of a new ArcMap document is zero, a MapServer object layer will lose any rotation when added to a new ArcMap session. The MapRotation value does not change, only the display of the MapServer Layer.
