When setting up a backup image server, I start with not knowing how much space I will need to store my images. What would be nice is to install and run a utility from the image server (using domain admin rights) and have it scan all of the network computers it finds and then report back the total amount of used disk space on each drive on the computer. Maybe a script could do this using psexec? I just need to enumerate the domain list (which I have done using psexec I think), then using the supplied credentials attempt to connect to the admin share of each drive of each computer and then report back the total amount of data on each drive. It would great to also see total drive size as well.
