Comment 75 for bug 462169

I just installed the latest 10.04 (including updates) and the same
problem happened to me.

In case someone might find this information useful,
this is how I fixed it:

In file "/etc/init/smbd.conf"

change this:

  start on local-filesystems

into this:

  start on (local-filesystems and net-device-up IFACE!=lo)

(which is how nmbd is also started, btw).

Hope it helps.
