I configured the system to auto-mount NASs (or samba drives) in my home network in openSUSE 12.1 KDE.
Dolphin displays mounted NAS drives in the drive pane on the left, but it fails to access those drives when I hit the icons on the drive pane. I can access those drives when I get there from root >> /media/NAS_mounted_directory, though.
How can I access NAS drives directly from Dolphin?

What path is shown in Dolphin when you click on the mounted NAS drives?

Sorry for the late reply.
On the left-hand drive pane, it displays "fileserver0 on //192.168.1.103" for the drive "//192.168.1.103/fileserver0". But I am not sure what pass Dolphin is trying to access because I don't know how to know the exact url for Dolphin drive entries.

If you click on the entry on the left hand pane, what url is shown in the Breadcrumb? (You may need to click just after the end of it)
