Sample tool assigns zeros to NoData cells

Discussion created by jgrand on Oct 13, 2010
I'm using the Sample tool to extract raster values for multiple grids at point locations using ArcGIS 9.3.  Points that are located in NoData cells are being assigned zero instead of NoData or -9999.  Does anyone know why this is happening?  Is there some setting that I need to change?  I can't find anything in the environment settings that looks relevant.
