Problem running Region Group tool

Hello all,

I'm simply trying to run the RegionGroup Spatial Analyst extension tool in ArcToolbox.  For some reason, when running this against a large raster (northern California), the tools runs 'successfully' - meaning it completes without error - except that the output has a data anomaly - whereby there are striped bands across the output.  The cells in these striped bands also have large integer values (e.g. 1991 while all other values are 1, 2, 3, 4, etc. for each unique group).  This tool problem has been repeated by different people on my team.

I'm seeing this same RegionGroup tool problem in ArcGIS Desktop 10 AND ArcGIS Desktop 10 Service Pack 1.

Can anyone confirm this same problem - or recommend a work around?

Thank you
