[Samba] bundled version not configured?

[Guy Steuart]

I am trying to backup files from a linux box to a windows box.
The linux seems to be bundles with Samba2.2.8.
It also seems not to work as I can't start the daemon or even find some of the expected files. Is it likely it was never installed or configured?
How do I get it running or is it better to download a new version and should I uninstall first? How?
