15.04 - Mounting using CIFS failing with "No such device or address"

---

I'm trying to mount a cifs share using:

sudo mount \
    -t cifs \
    -o credentials=$HOME/.smbcredentials \
    //server.example.com/Common/Share/Path /mnt/mountpoint

Which fails with:

Retrying with upper case share name
mount error(6): No such device or address
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Watching /var/log/syslog shows that there is some sort of dns problem:

Jun  4 18:06:12 laptop key.dns_resolver: DFSAPP03: No address associated with name
Jun  4 18:06:12 laptop kernel: [ 1807.650756] CIFS VFS: cifs_mount failed w/return code = -6

Does anybody know what the return code -6 means, or how I might go about debugging this problem?
