I been using drive backup server edition ver 10 build 9105 with no problem when I need to back up file on my network as it was always showing the letter of my mapped network under "this computer". I upgraded to ver 10 build 10444. which has "smart backup" that I don't see my network letter under "this computer" . I need to back up that network drive like I used to do. I changed nothing. my network is mapped to a letter.
