In order for symbols to scale, the map must have a reference scale set and the layer must support symbol scaling. Use ScaleSymbols to activate or deactivate a layer's symbol scaling. If a map does not have a set reference scale setting, ScaleSymbols will have no effect. Use CanScaleSymbols on IMapLayerInfo2 to verify if a layer supports symbol scaling. A reference scale is set within the original map document.

You can set a new reference scale for the MapServer object by accessing the IMap interface through IMapServerObjects2. This should be done with objects in a non-pooled environment.  Changing the state of pooled objects this way will lead to unexpected results.
