problem with DTS package

have a DTS package which utilizes an "Execute Process
Task". This task calls a batch file on my server. I keep getting this error trying to run the DTS from sqlserver:

"CreateProcessTask 'DTSTask_DTSCreateProcessTask_1': Process returned code -1, which does not match the specified SuccessReturnCode of 1:

Does anyone know what this error mean? TIAWhat is the level of service pack on SQL & OS?|||Possibly the batch job you are calling is producing an error. Try executing your batch job from a command window and inspect its result.

kbk|||Also enable DTS package logging for more information on this behaviour.
