I need to defrag a drive on my network. However, the user does not have an administrator account. How can I defrag this system with out logging in myself and leaving me logged in overnight. I do not want to do this cause it will allow the user admin privledges before I can log off. I am using Windows 2000 pro and have tried running command lines w/ runas but do not know of any cmd line for defrag in Win2k Pro. In XP it is defrag. Any help would be great.
