You should be able to mount that particular drive and have the mac remember the address; I’m assuming that she’s already using Samba to mount the drive like this:
In the finder: Go -> Connect to Server (or hit cmd-K)
type in the address like this:
smb://servername/directory/directory/ad nauseum
Before you connect, click on the little “+” button next to the address and it’ll dump it into the list below.
Hope this helps.
