i am trying to use the IDW tool to create a thematic map of an area. but the task is not completing and meets with an error which tells me that the background server threw an exception. please help me!
Without more information, perhaps your workspace environment setting is in a location you do not have permission to write to?
Or, try moving files to your local machine, maybe.
Disable the background processing and run the tool again (Geoprocessing > Geoprocessing Options > Uncheck "Enable Background Processing").
