ntbackup question

I've got a client that has a tape backup (onstream ADR 30 USB). After months of playing with it on and off, I've finally gotten it to work properly. In Win2K, sort of. I can make backup jobs (ntbackup) and it executes them fine, but I can't delete the jobs, or rechedule them. Anyone had any experience with deleting jobs or recheduling them? The software that comes wiht the drive is fatally flawed, and does not work properly under Win2K professional.

I gave up on NTbackup years ago...
Look into tapeware....

Thanks man, I'll have a look see.
