Sun E5000 running Solaris 8

I receive permission denied error when attempting to cancel a print job as root, user, or lp.
I found a tech tip that said to remove the tcp lp listeners but that didn't help. I can clean the queue using the old sun lpc command but my users need to be able to cancel their jobs themselves.
I have 4 systems running similar applications and the O.S. is the same but only the one system has the permission denied problem.
Any and all help would be greatly appreciated.
