your mention of the /rp parameter suggests that you are creating the scheduled task using schtasks.exe. Do you get that error when you try to create the task, or when the task tries to run? If the latter, examine the task on that particular system and
on one where it worked, and see if there are any differences.
Otherwise, post the actual command you are using.
