output raster <empty>

Discussion created by loganj on Oct 17, 2011
we have a computer lab installation of ARCGIS 10.0 (ArcInfo license). The PCs get the license from a license server. We thought everything was ok until our class started on Spatial Anlyst. No matter what tool we run, we end up with the error box, and the Results window shows that the output raster is empty. Has anyone else run into this issue with a lab installation?
