Remove multiple clients in a group from a backup schedule

[System_Shock]

Hey everyone...

First time here and a newbie Networker. I was given a task of
correcting a mistake made by someone in my group. This person
inadvertently added over 400 clients to a backup schedule and now they
need to be removed. The only way i know how to remove them is to click
on their job from the gui mgmt. console , hit properties and under the
general tab un-check them from the backup group. Any help is greatly
appreciated.

Thanks,

Rich
