A tip on SMB shares form MAC OSX HINTS
“At my work, we have a large number of SMB shares, and for some reason they stop showing up on desktops sometimes. If you look for them in Terminal, they are mounted, but they are not in the Finder anywhere. If this happens, here’s one way to get them back.
- Launch Terminal and type cd /Volumes
- Type ls to list the directory’s contents, and find the volume name in the list.
- Type open volumename, where volumename is the name as shown in the prior output.
A new Finder window will open with the root contents of the volume you chose, and the icon will then appear in the Finder window and on the desktop (if you have network volumes showing on your desktop).”
